The rabbit hole within the DMT realm is infinite and can always get more intense IME.

I would try to not get too hung up on whether you broke through or not. It's usually very easy to know when you have though, as everything about it is undeniable. I've said this before, but when you are pre-breakthrough you are seeing visuals, and when you truly get there you become the visuals.

Try take each experience for what it is and if you feel comfortable, up the dose a bit and see where it takes you.
