I would have to investigate your behavior more thoroughly to understand its purpose and origin. Perhaps it’s a type of disassociation. The basic definition of disassociation is a partial, and in some cases, complete disruption in an individual’s consciousness or psychological state of functioning. Disassociation can result from trauma. In cases of trauma, an individual may unconsciously disconnect from a particular situation because it is too psychologically painful. Disassociation can be thought of as a psychological defense mechanism.
If what you are experiencing is disassociation, the scenarios you are creating may be helping you function. As I mentioned earlier disassociation is a type of defense mechanism. Defense mechanisms serve as a form of psychological protection. You may be engaging in scenarios in an effort to distract yourself from some painful aspect of your life. The scenarios may be protecting you from feeling painful emotions. While they serve as protection in the short term, they can be psychologically damaging long-term. Defense mechanisms block or buffer a painful reality but eventually an individual needs to face the underlying problem.
It would be interesting to know how long each scenario takes place, what prompts them, how you act them out, and how you feel about them. For instance, can you stop engaging in them easily or do you feel that you have to do them? Do they make you feel better? Do you feel more compelled to do them when you’re upset or stressed out? Have they increased over time? Those are some questions that would help me to understand what they are and why you engage in them.
I am sorry that I do not have a definitive answer for you. I would suggest that you keep researching the issue to see if you can uncover evidence of this occurring in relation to a particular mental health disorder. If the scenarios are significantly disrupting your life and are causing you distress then it is advisable for you to be evaluated by a mental health professional. Thank you for your question. I wish you the best of luck.
