i found a small dose of LSA , say 20-30 MG seeds gave me some vivid dreams.
the awesomest dreams ive ever had were when i was extremely sleep deprived. after tweaking for 2-3 days solid, to the point where u start to hallucinate and start dreaming while your awake. when i finally do go to sleep my dreams are intense and somewhat contollable.
like once i was having an astral dream where i was flying around where i grew up. it was so realistic i can still remember trying to swoop like a bird, but you fall unnervingly fast so its alot harder than you would think!
my theory is that when your so extremly tired you start to use your unconscious brain more, because the conscious one is so fucked. then you go to sleep and rest your conscious brain, but since you are somewhat accustomed to using your unconscious one at that point, you can sorta control your dreams a bit.
note im too lazy to attempt to stay up for 3 days without a healthy serving of meth, the drug itself may have some role in this .
