Me right now too. I was thinking about this episode recently. I couldn't figure out what it was supposed to be comparable to. I guessed dodging traffic on a highway, but that didn't seem right. Getting hooked on drugs makes sense though.
My life would be a-lot better if I could get addicted to drugs. Sadly my brain puts a hard stop to that and I just stop doing them mainly due to severe depression. I even used to smoke for like a month of nicotine vapes only to just quit outright.
Oh yeah due to lack of chemicals in my brain that lets me get addicted to things alongside having broken dopamine pathways. I can't remember jack shit and the only thing I do remember are the things that my autism hyper focuses on or certain types of delusions or fantasies I have going on in my head including dreams. Sadly I also broke the more creative side of my brain after tripping too hard and now not even LSD can make me hallucinate as I can choose not to. It's probably for the best that I'm grounded so far into reality that my delusions and fantasies are just intrusive thoughts now more than anything else.
I have had a theory for many years that part of my autism is related to a unbalanced endocannabinoid system where i do not make enough dopamine as part of the natural reward process.
I bet you already tried full spectrum cannabinoid oil containing both cbd and thc. But if not i highly recommend it. But not to get high. I personally found a good dosage that allows me to boost the ecs the right amount to have it function more similar to others.
I am curious to know if you ever tried dmt? Real Breakthrough does not compare to conventional psychedelics but if you already state that to much lsd ruined your (creative) right hemisphere i am not sure i can recommend it.
What can absolutely recommend for intrusive fantasy is recreational immersive daydreaming. I have a feeling you may already be doing this but in the form of Maladaptive daydreaming
What i realized for me is that its all about balance in your mind. I love working with logic, structure and math and general very left hemisphere stuff. But i also have a real need to stimulate my right hemisphere trough a creative process.
If i don't foster my creativity and ability to fantasize i become distressed and borderline psychotic making me unable to work with logic and structure.
I always make sure i have acces to a creative outlet, be it a specific task on my job (i am fortune to have alot of freedom though) or a side hobby.
Whenever i have time alone (which is also a need many neurodivergent people share) i tap into fantasy to simulate a world around me where i have absolutely creative control. Its also fairly useful because you can simulate situations from real life to study them up close.
Yeah I already smoke weed and it makes me feel "normal" per say. But I only smoke it at work and I don't really smoke outside of work in general because I either forget or just don't want to. Honestly I think I should force myself to smoke more but for some reason I never do. As with the creative outlet... Uh yeah I need one badly. It's a shame. That i'm literally bad at doing any creative work or having the will power to fully realize the worlds I create inside my head from time to time. I'm really really lazy. Granted I guess most of the things I would create would be extremely experimental at best or bad to play at large. In terms of games I would like to make.
