I been astral travelling a lot and know exactly how to do it. but i have stop for a very good reason, It is not what you think so please be careful of the dark force if you're trying to astral travel.
Astral traveling can be fun and exciting your travelling into the unknown. you gain self awareness and all your senses heighten through the roof. Suddenly you realize you no longer speak or move see or feel the way you did like here on earth but don't let that fun fools you it is indeed demonic unless you go with protection.
Keep in mind you are going into another dimension a spiritual world. A world of super consciousness. it defied the law of physic. at this point you cannot denied '' God existence'' make sure to please call on Jesus when you need help. Its all i can say. Believed me all its not all cookie and cream. I can't stop you from doing thing you so wanted to do. I also don't want to spoil your fun but as a good fellow human being I feel it is necessary to give you a head up.
