What happens when you take lsd?

you either have a good or bad trip, when i did it my walls, the tress, the grass was moving like waves. Music was better and i was just happy the whole time. Your eyes/pupil will open up so you will look crazy high. Don't do it if your parents are around. Effects supposly last 12 hours but the times i did it, it would only last me 2-5 hours. i must have had some weak stuff but i did hallucinate and they where all amazing trips
