No possibility that it was the acid that led you to believe you experienced telepathy, right?
Pretty much, have experienced the effect myself and I've always assumed it was just a case of empathic synesthesia whereby ones perceptions of body language trigger the linguistic representation of what that body language represents.
From one's own perspective, while tripping absolute balls one can glance at a friend and literally hear a voice, much like their own internal monolog that corresponds to how one perceives them to be thinking much like one can look at an object that one associates with a colour and observe that colour bloom around it like a halo.
Nothing really supernatural about it really.
Derp. It was a joke, lighten up. "rolleyes", lol
heh, well, joke or not it's still a thing that many often experience.
