Well, since this first experience I have done it 3 more times.
The first was in the woods at dusk, all I really remember was the ground telling me to come back inside becase I wasn't supposed to be out of the ground... and I remember seeing the shape of a car in the ground. I had lost all connection with reality and I really thought that I was supposed to lay down on the ground so that I could be sucked back into the soil.
Second time I was at a party next to a pool deck with people swimming in the pool, I thought it was going to be a bad idea but it was probably the funnest experience of all 4. Everyone was really nice while I tripped, they told me jokes that made me fall out of the chair. I remember seeing waves of color in the backround, and I attributed this to the 3 beers I had before smoking. I didn't lose grip of reality, but it was intense as hell and I didn't come down as fast as I did all of the other times (again probably the alcohol).. and when I did come down i went back to being drunk and that scared me, because I had almost forgotten about being drunk and I thought I was still tripping.
Fourth time, back in the woods again, bigger bowl, way more intense. The woods instantly became my house, but it was a room I had never seen before, but I knew it was my house. Two entities, which I perceived to be my mother and sister, told me to come with them. I can't really explain the rest, but it was as you guys described, leaving reality and being put into a new plain of existence. As I started to come back to reality I got really angry that I couldn't do what the woods wanted me to. It was like I was getting yelled at for not doing something, and I didn't even know what to do. I was angry that I couldn't understand what had been said to me.
Also, I realized I had been sweating buckets. Bugs where biting at me and I looked like I just got out of a pool. That made me even more angry.
So, the last time was a whole lot different than the first. First I just laughed and felt the "pushing" feeling. The fourth time I lost touch with all surroundings and I just kind of stared as reality was shattered and reformed itself... I can't say which experience had actually been the "break through" experience, but I defenitely know I got the full effects of this mind blowing substance.
PS. I know I have to use a torch lighter, take a massive hit, and hold it. My minibong works fine, and I don't have access to any bigger bongs anyway. It worked for me. And I did have a sitter. PS sorry this post is also sort of a trip report... I'm going to write one up with a lot more detail when I get the time.
