to kind of add on the the astral travel question- 1. you cant get lost. There is actually a cord connected from your stomach ( sacral) chakra from your astral body, to your physical body. it cannot be cut by entities and is supposedly cut when you pass onto the next life. Regarding "ghosts," don't call them ghosts, because ghosts refer to a person that has passed on. There are many different types of beings in the astral, some are high-vibrational and some are lower.
