I think i've had 1 maybe 2 breakthru. But i'm not sure. I've seen really cool visuals and patterns and slightly become a part of everything around me and felt like i was floating in the room on a 40mg hit. But i was fully aware of where i was. Is that a breakthru? I don't think it was, but i don't know what constitutes a "breakthru". One time i saw a ball of light and became one with it losing my sense of direction and gravity and i know i was somewhere else. Is that a breakthru?
One more question, Should i keep my eyes open or closed? Does it matter?

You could also venture incrementally further to learn your sweet spot, without going overboard (overboard = forgetting everything completely).
