wow i have the same problem pretty bad too and I dont even smoke weed anymore but it happens to me often when I'm sober and a lot more if im messed up. I think it is some type of consequence of any psychedelics because I already had that problem before I ever tried DMT. Ive used a lot of ecstacy and lots of ketamine and lsd so i think they are all connected in underlying ways that sort of distort your ability to differentiate between people. Sometimes I see people and I feel like they look familiar or like someone I know or knew and then I think about it and I cant really be sure if they really do or not! kinda disturbing. It may all be connected to the oneness of everything too which drugs of course have opened your mind to. If you've ever seen the movie called SCANNER DARKLY with keanu reeves its about a drug called substance D that after so much use the user cant feel the difference between different objects or confuses people for others until he basically loses consciousness. its a good movie creepy you should watch it
I am one crazy bitch don't believe anything i say grrrruhhh
