That's not medium rare, just rare. Sweet, delicious rare. I want some.

It was that "we will walk through the fire" one. But I know when I wrote it down, when I was tripping, in my head I was writing down the meaning of life and the universe and the nature of consciousness. Acid is weird. I never did it again, it's not that it wasn't (mostly) enjoyable per-se, it's just I was so relieved when I woke up the next day and everything had stopped moving.

Edit: Just for a nostalgic laugh, for any of you who've never taken acid, here are a few bits I vaguely remember from my trip (was about 20 years ago now):

1. At one point, I believed I'd become a cartoon character. The whole world looked to me like a quite crudely drawn, 2D Family Guy style animation.

2. For a while, people's faces were morphing in to long, rat-like features and it looked like they were laughing at me in a very sinister way. I didn't enjoy that part.

3. I was a genie for a while too. Like, I wanted a sandwich and suddenly I had one and I was eating it. No sense of any time passing or any memory of doing anything between wanting a sandwich and having it in front of me. I realised I'd run out of cigarettes, then suddenly boom a fresh pack of cigarettes were in my hand. I named my genie self Barok the Great.

4. In a later part of my trip, I experienced going and making the sandwich, just completely out of place in time. Like splicing a video in the wrong order or something, only that's what I actually experienced.

5. I could see sound waves coming out of speakers. That was really cool. And you can just be looking at a wall or something and it just melts and blends and becomes the coolest looking kaleidoscope thing, or something like that. The visuals are a very unique experience.

6. Trails. If you ever do take acid, you'll 100% have this happen. You move your hands and you just see an after image of your fingers, like a duplicate, trailing for a few seconds.

7. It can be bad too. My trip eventually went a bit sour, I can't remember why but I had some negative thought and it just manifested in some way and I remember I really wanted the trip to end and to just sober up but I couldn't. That's the downside of acid, once you're in, you're in for as long as it lasts and it lasts a long time.

8. The mental part. People don't often talk about this bit but it's not just hallucinations and weird philosophical thoughts and feelings, when you come up it feels like you've done about 20 bong hits back to back. It's intense. That bit does seem to mellow out later though.

I took acid once when I was 18 and remember clearly feeling like I was one with the universe and completely understood everything there was to be understood. It was like a completely transcendental experience of consciousness where my being and the whole universe were the same thing. I wrote down some notes about the secrets of the universe while I was tripping.

The next day I couldn't remember what any of the secrets of the universe were and it turned out the notes I'd written were just lyrics to one of the songs in the musical Buffy episode.

This sort of thing seems to be a common experience with LSD.
