Interesting question, and probably unique to each person. For me, I usually go through a routine of sorts, in which I experience impossible colors, shapes and maybe sounds which seem to be the precursor to the experience. For example, I take 2 or 3 nice big hits. Things might start to bend, or liquefy, or change colors and texture. Patterns start to emerge on objects, for instance the carpet will form geometric patterns, the walls, all of it. Then, sometimes my trip stops here, or it doesn't progress past this point. This is what I call a soft trip. However, sometimes depending on how much I smoked, how well I feel, how much anxiety I have and so on the trip can progress to the next level, which is always a breakthrough experience.
This, for me, is where things get amazing. At this point, I typically get this overlay on reality, its like a pattern of light, little oblong circles of all different colors form this very impressionable overlay like wearing glasses. I can blink and look around, eyes open or closed, its there. This last about 10 to 20 seconds. After this, I usually see a large amount tunnel, at which point I believe I start to travel through it, and through this tunnel I see geometric lights and colors shooting around everywhere. I couldn't tell you what colors and what shapes specifically, its like every shape and every color all at once.
Finally, after this traveling type experience, I generally find myself experiencing very real, very vivid and very alert entities that always want to interact with me. The last time I got to this point, just 2 days ago or so, once I went through the tunnel I met this guy who was standing on the edge of a platform up in the clouds, he was wearing some type of costume with a mask. He was surrounded by two women figures. He looked at me and said how deep do you want to go, at which point he started to literally remove chunks of reality in the sky in the shape of puzzle pieces, and behind each puzzle piece that was removed was a doorway into the universe. As I started to go through, the trip started to wear off, and he told me that we would continue where we left off...
So, that was my last experience, kinda excited to see if I will actually continue there. Though, the whole part where I see the pattern of light-shapes and see the tunnel and the multi colors geometric patterns are all pretty common and have happened dozens and dozens of times... It's what happens once I get through that phase that is always unique and amazing which give me the breakthrough type experiences.
