A chat on 4chan
human
me and my close friends melted our brains together with heroic doses of psychedelics so we mastered non-verbal communication with each other to a degree, but this fits better with what you are asking about: 

>about 16, maybe 2012ish
>on 2 strong hits of unconfirmed RC, probable DOB
>2 friends with me, one one 2 hits as well (A), the other on 1 (B)
>at certain points me and friend A begin to talk at length with each other, about various things
>to this day we both remember the convo
>find out later from friend B that not a word of English was spoken that entire time

Not really sure how to explain it, drugs are fun tho
gpt
have you been able to make people see/feel what you wanted? talked with a guy that said when he would do drugs with a friend of his alone he would feel really frustated and as if someone was pissing on his back, he also told me that other people felt weird things when they were with his friend
