I dont believe in that stuff about Dmt on the brain. Even with low doses I see beautifull things, things I cant imagine even in my dream-meditation previous to sleep... I see things, but just like my common dreams, normal things, and dreams are not psychedelics, even my lucidDreams... So I thing human brain produces a very low dose every night or our dream molecule is not Dmt, maybe similar, but not Dmt.

Just my humble opinion.... Peace
