I'm pretty sure this Idoser stuff delves into spirituality, and I've always heard women are more sensitive to these kinds of things. Example: My friend and I were visiting this supposedly haunted place and the female really started to feel sick, we later asked my friends sister who has been a wiccan...

Yes, the deeper i get into the 'trance state' or whatever, the more I feel it. When I get really deep, it feels like I have a copy of my body hovering just right above mine. Kinda weird

This is exactly what happened to me. I listened to the Astral dose and throughout I felt slightly above my body, and when it was over and I took the headphones off and experienced what you said. Everything 'echoed'
