What I think about:
Some time I speculate about a topic I've been studying. I've been learning a lot about cacti right now. So I've been thinking about the potency of the hybrids I have, and how I could spend the next 30 years revolutionizing sacred cacti. Then I start thinking about Alexander Shulgin, and fantasize about how I could study chemistry and start finding unknown drugs in cacti.
I also have a lot of power fantasies. Like my work place getting robbed and I somehow stop it. Stupid stuff. I'll have these grandiose monologues in my head. sometimes they are super epic and I get myself super pumped. Other times I realize that I'm just rambling to myself in my head. So I stop. I monologue so much.
Then the sexual fantasies. Those are usually best when I'm driving or super high and listening to music. They go all over the place. I'm even shocked with where I let some of them go. We'll just leave that there.
Lastly I can have really bad ruminations. To the point that if I'm by myself I can sucked into the fantasy that I can't even control where it goes. I'll relive things from my past, but an alternate version. One where it went bad, and each time it's repeated it gets worse. Or I'll imagine conversations. These are 50/50 on if they are bad. Some are really good and help me understand something better. The other times it's just negative. They'll go sour really quick and sometimes really hurtful things are said.
I would say it's escapism, but it can take up a large portion of the day. To the point that my day dreams often override my sense of sight and the fantasy plays, while I still manage to interact with the world in a normal way. Just on autopilot. I still know the difference, but I do find myself responding out loud or acting out my day dream. I hope this just means my imagination is active.
