Was tripping on acid in a room with 3 others tripping on acid. For over an hour we we all thought we were talking and having a full blown in depth discussion about space with each other. We kept on laughing, pointing and nodding at each other.

However we started to come down and all of us at the same time realised we hadn't been having any conversation what soever, the room was silent, nobody had be saying anything out loud at all and everything was in our heads.

We were all talking about the same subjects and having a discussion but none of us were speaking or making any vocal sounds. Too this day I still believe there was a connection on a deeper level between us on that night because I can not reasonable rationalise how on earth we sat their in silence and had conversation with each other.
