Imagined sexual or erotic material. A fantasy can be curious, symbolic, intrusive or arousing without being a wish, plan, identity, preference or consent to enact it.

In brief
Imagined content is not evidence of intended conduct.
Fantasy is mental content, not a contract with reality. People may deliberately imagine a scenario, notice an uninvited thought, enjoy a theme only in imagination or use fantasy creatively. Meaning depends on the individual and cannot be reliably inferred from the storyline alone.
Common, varied and personally interpreted
Survey research finds wide variation in fantasy themes and frequency. Labels such as common or unusual depend on the sample, wording, culture and historical moment rather than a natural boundary.
The same theme can serve different functions: curiosity, novelty, emotion, symbolic reversal, memory, soothing, arousal or creative play. Researchers cannot read its meaning without the person's account.

Fantasy
An imagined scene, theme or sensation that may or may not be wanted, recurrent or arousing.
Desire
A felt interest or motivation; it may overlap with fantasy but does not automatically follow from it.
Intention
A plan or commitment to act. Fantasy alone provides no evidence of intention.
Behaviour
What a person actually does, governed by consent, ethics, safety and law regardless of imagination.
Fantasy is not a wish or identity test
Enjoying an imagined scenario does not establish that someone wants it to happen, would consent to it or identifies with every role in it. Distressing intrusive thoughts may be especially far from desire.
Equally, a fantasy need not be decoded. People may keep it private, discuss it, adapt only selected elements or decide it has no practical significance.
If adults discuss enactment
Moving from imagination to activity is a separate decision requiring lawful, specific and continuing consent from every participant. A fictional lack of control cannot remove real-world control.
Discussion can distinguish the appealing element from the literal plot, set exclusions and preserve an easy way to stop. Some themes should remain imaginary because real enactment would involve non-consent, illegality or unacceptable risk.
Distress and support
A fantasy is not clinically problematic merely because it is uncommon or embarrassing. Relevant concerns include significant distress, impairment, loss of control, serious risk or non-consenting involvement under an applicable diagnostic framework.
A qualified, non-judgemental clinician can help with unwanted intrusive material or distress. Seeking help does not require treating every fantasy as a hidden intention.
