Initiation!

I was with a group of people who had to go through some overnight ordeal as part of some secret society initiation.  Some of the people including myself had been through it before and knew how dangerous and scary it truly was.  People in the last session had gone mad from whatever they saw.  We all started to walk toward a cave where the initiation would take place.  I looked on the other side of the cave and there was another cave with a very well marked opening.  I knew we were not allowed to look over there and worried I had done something wrong.  We walked through a dark area and on the wall across from us was a spotlight lighting up two doll faces.  The doll faces were all white.   When we got to our destination there was a large square hole that no one wanted to enter.  The last thing we had to do before starting our ordeal was to take some hallucinogenic substance.  I just pretended to take mine. The person next to me took the substance and immediately went mad and jumped into the hole.
