Maladaptive Daydreaming: Immersive Fantasy, Impairment and the First Treatment Trial

The short answer

Vivid fantasy is not inherently a disorder. Maladaptive daydreaming is a proposed clinical construct describing immersive daydreaming that becomes difficult to control, distressing or disruptive to ordinary life. The important question is not how imaginative someone is, but whether the activity repeatedly displaces sleep, work, study, relationships or other things they value. [1,2]

Research has grown, including a meta-analysis and a randomized intervention trial. It remains a developing field. The experience can deserve help even while researchers debate classification, and recognition should not become permission to overlook co-occurring depression, ADHD, dissociation or other difficulties. [1]

Immersion and impairment are different dimensions

Someone might invent detailed characters, repeat scenes with music or spend long periods inside a continuing story. That description alone does not show impairment. For another person, the same activity may feel compulsive, consume unwanted hours or become the main response to distress. Clinical interpretation depends on the impact and degree of choice. [1,2]

A useful assessment asks what happens before, during and after the experience. Does it follow loneliness, boredom, anxiety or a particular cue? Is it pleasurable, distressing or both? Does the person know the story is imagined? Are there other unusual perceptual experiences? These distinctions help avoid confusing several different phenomena.

Knowing that a fantasy is fantasy is relevant, but it does not settle every diagnostic question. Attention problems, dissociation and compulsive behavior can overlap without being the same thing. A label chosen from a brief online description may capture part of the experience while missing the difficulty most in need of treatment. [1]

What the meta-analysis found

The 2025 meta-analysis included 40 studies involving 24,977 participants. It found positive associations between maladaptive-daydreaming measures and depression, anxiety, dissociation, obsessive-compulsive symptoms, ADHD and other forms of distress. It also examined associations with loneliness, emotion-regulation problems, shame and self-esteem. [1]

That pattern supports taking impairment seriously. It does not show that daydreaming caused each associated condition, that every participant had a clinician-confirmed diagnosis or that one underlying disorder explains all cases. Self-report scales can share general distress content, and selected online samples may differ from the wider population. [1]

The size of a combined sample should not hide the design. Thousands of correlational observations can improve precision about an association while leaving causal direction unresolved. Daydreaming might contribute to lost opportunities; distress might increase fantasy use; both might reflect shared vulnerabilities. More than one process may occur in the same person.

The first intervention trial

Herscu and colleagues randomized 557 people to versions of an eight-session self-guided internet program or a waiting-list condition with internet support as usual. The interventions included psychoeducation, motivation work and mindfulness; one version also included self-monitoring. The publication reported improvements in daydreaming symptoms, frequency and functioning. [2]

The self-monitoring addition appeared to offer a short-term advantage, while the two active interventions were more similar at longer follow-up. Reported gains were maintained at six months. Those results are a reason to pursue replication and better treatment development. [2]

They are not equivalent to proof that meditation works for everyone. Many randomized participants did not complete the program, the sample was self-selected and the comparison did not match the active intervention for all expectancy or attention effects. Participants also knew which activities they were doing. These factors limit how confidently one can generalize the result. [2]

The abstract's reporting of completion and arm counts is not perfectly internally aligned. This review therefore avoids presenting the listed arm counts as a clean reconstruction of participant flow. A precise attrition analysis would require reconciling the full paper and trial reporting, rather than silently repairing an inconsistency.

Improvement is not one universal percentage

The trial reported clinically significant and reliable improvement measures. Those labels refer to particular statistical definitions and analysis samples. They should not be converted into the statement that a fixed percentage of all people with the problem will recover after a short online course. [2]

A person could spend less time daydreaming but remain depressed, or continue to imagine richly while regaining control over work and sleep. These outcomes matter differently. The best treatment target is usually improved functioning and flexibility, not erasing imagination.

Similarly, the first positive trial does not establish medication efficacy. Case reports and personal accounts may generate hypotheses, but they are not substitutes for controlled comparisons. A medication used for a co-occurring condition should be evaluated for that condition rather than described automatically as a proven daydreaming treatment.

Why total suppression can miss the problem

Trying never to imagine anything can be unrealistic and may turn an ordinary mental activity into a source of shame. It can also leave the original difficulty untouched: isolation, anxiety, unmet social needs or a lack of tolerable rewarding activities. The association literature supports assessing those accompanying difficulties, without proving a single explanation for every case. [1]

A clinician may explore what function fantasy serves and which real-world demands feel unmanageable. Practical goals could include protecting sleep, reducing unwanted lost time, completing an essential task or building one valued activity outside the fantasy. These are examples of individualized goals, not a protocol validated independently by the two cited papers.

What a useful record looks like

A brief record can note approximate time, triggers, controllability, distress and interference. Avoid false precision: a reasonable estimate is more useful than spending excessive time tracking every moment. If recording becomes another compulsion or increases distress, discuss that with a clinician.

Bring examples that show both the appeal and the cost. Saying that the activity helps with loneliness but repeatedly delays sleep gives more information than simply calling it an addiction. The clinician can then examine mood, attention, trauma, compulsions and other possibilities in the same assessment.

Safety and the research frontier

Urgent help is appropriate for suicidal intent, inability to meet basic needs, severe sleep loss or experiences that involve losing contact with reality. A proposed daydreaming formulation should not delay assessment of those problems.

The evidence currently supports a balanced conclusion: impairment associated with immersive fantasy is real enough to study and address, and early treatment research is encouraging. Classification, mechanisms, independent replication and comparative treatments remain open. A person does not need certainty about every one of those questions before asking for help with the parts of life being crowded out. [1,2]

How to read this review

This is a critical narrative synthesis of selected published research, including reviews and meta-analyses where available, not a new statistical meta-analysis. It is not an exhaustive systematic search, an individual diagnosis or a treatment prescription. Source identities and abstracts were checked against Europe PMC records indexed from PubMed on October 26, 2026. Abstract-level verification does not establish every detail of full-text methods, adverse-event reporting, corrections or investigator conflicts. Those gaps limit confidence rather than supplying permission to assume favorable results.

A reference number links an explanation to its source; a PubMed identifier locates a publication and is not a quality score. Studies reanalyzed in several reviews are still the same underlying participants. Clinical recommendations, observational associations and randomized treatment comparisons answer different questions. Where the evidence concerns a mixed diagnostic group, this review does not present that average as an established result for every diagnosis. No affiliate products are ranked here.
