My first acid trip was really intense in that regard. Not just browsing GAF, but the idea of using the internet to basically be everywhere I would want to be was just so overwhelming. When a friend (basically my trip sitter) sent me the link to a thread full of bish banned gifs, I felt like literally falling towards the message board while at the same time having to dodge all the bishs. I was laughing and crying so hard. At one point I just closed my eyes and went into the fetus position. When I started moving again after five minutes or so I looked at my TV (I had my laptop hooked up to it) and, seeing as I was still in that thread, proclaimed proudly: "I have arrived."
But I'm done with those things now.
