DO NOT DO IT ALONE. Have someone you trust there to monitor you. With 15x I did it alone and for awhile I had no control of my body movements and could have injured myself. It's mainly mental, you don't so much "see things" as your field of vision seems to be a myriad of chaos. This isn't a party drug you use to get wasted like alcohol or cannabis. This is a very spiritual concious altering drug.

I have yet the pleasure of doing this, but I think the best setting would be outside on a summer dawn or dusk laying down on the grass looking at the sky out in nature.
