I could see that happening. It's different for everyone, and it's a very fluid experience. Something can go from scary, to delightful, or vice versa on a whim. I'd have to describe most psychedelic trips as very lucid dream-like experiences. A lot of it comes down to where you are and whats around you. Mushrooms were my first time and I really enjoyed them. I was with close friends in a safe comfortable place, which I think makes the biggest difference. I would avoid horror movies at all costs, and if you have popcorn ceilings, oh man, watch out! You will see some crazy patterns when you look up. I think the worst part about mushrooms is eating them. They're sold dehydrated so they're gross looking and tough to chew. They don't taste that great, and supposedly they taste even worse fresh. I don't know if that's true, I refused to try them un-dried! The times I had acid it was either on small pieces of paper that you hold in your mouth, or a little drop of clear liquid put onto a hard candy. Decidedly much more pleasant to ingest, in my opinion. The other advantage of acid is that the dose is more controlled; potency of mushrooms can vary from batch to batch, so it's harder to predict how big of a trip you'll get from them. I think either of them would be good for someone who wants to try it for the first time. I've heard a lot of horrifying stories from my friends' experiences on shrooms.
