Dimensional travel and dissociatives are nuts and bolts, can't have one without the other! :D it's what makes me love them so much in the first place, I don't really know or care whether I'm escaping the rules of normal perception or just delving deeper into them but the stuff I've seen and experienced is bloody wonderful (and crazy) either way.
A couple of my favourite weird occurences include me and my friend both seeing ourselves out of each others eyes at the exact same moment for a few seconds, and a Groundhog day type experience where I lived out a whole normal week in the K hole, seeing how my current life would lead to everything going dramatically wrong if I didn't make changes, and then woke up and realised it had just been a trip and I was back to day one - got the chance to make those changes and make sure everything went okay.
You given Diphenidine a try yet? I've heard it compared to 3-MeO-PCP by a few, though only having tried Diphenidine and not 3-MeO I can't really say if this is a good comparison or not. I wrote a report though here:

I do love my dissociatives, maybe it's about time I get 4-MeO or 3-MeO after all.. or at least just get some more MXE in or something :D
