You just had a free DMT induced therapy session , the sleep apnea gave you a massive dose of natural DMT

Actually, I didn't add this but I know this is true. Part of my early morning meditation practice involves breathing and looking into the black until it opens up and images come to me. Usually it's some concept like people sitting around that continuously shifts in picture but thematically stays the same, or landscapes (geometric or organic), or cartoonish art madness. Sometimes it looks like I'm seeing a real place at some real time. Best results are if I havent drank alcohol and I've already slept a while and I'm up for some reason. After, I turned my attention to my friend.
