Hi!

So I've been meditating for several years now and I'm able to visualize things so well that it "feels real" from taste , touch, smell, look etc if I choose to. This is the first phenomena I encountered. Is this simply a placebo effect of sorts?

Secondly sometimes if I intensely focus on my audio sensory system I'll hear intense ringing, that almost sounds deeper than in my ears , has anyone else experienced this? If so what is it?

Thirdly This is the most recent phenomena I experience And basically I'll try and think of losing all senses And then I'm not too sure why but I feel this intense spinning sensation . Has anyone experienced this as well? And is there a name for it?
