I’ve read several of the accounts at Erowid and have (in my limited experience) never had anything approaching a “mystical” experience. But I did recognize a couple of aspects of your experiences.

My first several trips were using just the raw unenhanced leaf. No sensations of fear, but I also could never really remember where I’d been and the trips were short. I did always feel a sensation of being warm, and fuzzy and loved. I then graduated to 5X and 10X leaf. I had several similar experiences with a lot in common.

The first thing was that as soon as the drug took effect, I immediately snapped into another reality. Like you, I recognized this new reality immediately and I had no question that it was “real.” I was always amazed that I had “forgotten” that it existed. Unlike you, (and most other people apparently), there were no teletubbies, or speaking plants or other mystical creatures. It was just another world…just like this one only different. I did commonly experience things like fractals–the world would begin to subdivide into repeated patterns.

I usually smoked outside late at night (my wife didn’t want the smell of smoke in the house). On several of the trips, I felt that if I weren’t with my wife, I wouldn’t make it back to the “real world.” So I’d race from the patio into the bedroom and collapse in bed next to my wife. Not good. Broke a couple of bongs that way, because during this little journey I was completely under the influence. I typically wouldn’t remember much about the trip to the bedroom.

The final thing was that while under the influence I’d lose track of my body position. In the dream-state, my body would (for example) slowly roll upside down, and I’d feel that my “real” body was doing the same. It wasn’t, but it was so scary and uncomfortable that it would often pull me out of the dream-state–or cause me to spill another bong trying to right myself. I found that if I could lay in bed and hug a pillow, I could experience the rolling sensation without needing to return to regular consciousness.

After several trips, I simply lost interest in doing more. I haven’t had an experience in maybe 9 months. Although I’ve been thinking about it recently.

One more common experience for me: After smoking, I’d almost always feel incredibly aroused for about the next 24 hours. Just a little pleasant side effect.
