Here are some pointers... ***Watch what you think. Everything you think can manifest on the astral planes. So you don't want to be thinking about anything evil or you will attract it!
***Anytime you think you are scared and or lost, just think of your body and you will be back in it in a flash.
***Ever notice that when you are falling in a dream and you hit the bottom you always wake up quickly! That is your astral body snapping back into place.
***The use of drugs can lower your vibrations meaning you will not be able to travel to higher astral planes where the vibrations are higher.
***The reason you will want to travel higher on the astral planes is because you may have to escape an attack by a lower vibrating entity. They can not travel to the higher planes.
