Can someone give me some insight?

[Stimpy]

Hello everyone
Can someone give me some insight on this experience i had please?

Basically I'm listening to Monroe's hemisync "Into to focus 12" and what happened was this
the part comes when Monroe counts from 10  to 12 to put me into focus 12 and as he counted to 12 nothing happened for a while and then all of a sudden i felt like a click or a pop and my full Consciousness felt like it was inside my head like i would exist inside my head, the blackness in front of my eyes turned 3D i think and i don't remember if i could fell my body at that point.

So i watch the blackens for about 10 seconds or so and then all kinds of energetic sensations started happening which are hard to describe i felt as if i am slightly pulled up and i could see some colors swirlling around in the blackness which became much brighter at this point. I also experienced fluttering of the eye lids.
I was quite overwhelmed by these sensations and then the voice of Robert Monroe says now lets go back to focus 10  this completely destroyed my concentration and the sensations and everything stopped and i went back to focus 10

sorry for making this long if anybody has some advice please share
