Most experiences of people is floating over their bodies. I found women more prone to have the experience. I know most men who talk about it are not sure of what it is. to go into the astro realm by most science level authorities is to bet into the alpha state, that state between awake and asleep. very drowsy state. What you can expect is a whirling vibration like a baby heart monitor during pregancy sound. a incredible positive good feeling that is hard to describe. What you need to know is negative though can stop you from advancing here. Some people have gone into others house. while others respect other peoples privacy. Once you think of your body you will be in it. You will either be flesh or a measure of light ranging from a light glow around you and yourself a floating being all light. heaven and hell are real. by most religions there are several planes, realms demensions of each.
This is taken from my own, other people from surveys, and People in my Spiritual group. I did not label them and tried to make it generic.
