Experiences - can two people have the same trip on LSD?

Aquestion i have had since my first acid trip 11 years ago is can two people experience the same hallucinations at the same time?


My then boyfriend and i had the same amount of lsd and about five hours on wewere both having the same trip, we both stood and watched a space ship slowly move towards us in the sky from the distance until it was overhead, probably for about 20 minutes. we were both able to describe it identically afterwards. How can this happen ifwhat we were seeingwas a hallucination?
