Hemisink Meditation - I Did It to Day

i tried a guided meditation that uses these hemisink vibrational noises. When i meditate mindfully, all i'm doing is focusin on my breathing,. And what it does is it completely relaxes my central nervous system and washes out my brain. I won't say i enjoyed it. It sent me into quite a deep trance that i didn't enjoy. It felt more like i was being hypnotized.
