Some would say in doing so you can leave yourself open to demonic influences...and that the “spirit guides” they profess are just that..from the dark side. After all satan is well known to masquerade as an angel of light....interesting how often new agersuse the term “Light”....
Additionally is is known that people who go into deep meditation over a period of time can and do “suspend” their critical thinking abilities...which makes perfect sense.
The dangers are...,as Scott Mandlker teaches, there is a total preparation and later transfer of ones personality and being to another...willing done by the party because by then they have become so entrenched they have lost their ability to discern good and evil. “A suspension of critical thinking” does happen.
....”these meditations of going to other realms are actually states of altered consciousness that are the same as being hypnotized. This means that judgment and critical thinking skills are suspended. So one is opening himself up to influences from anywhere (demonic) and allowing experiences to validate this beliefs. This is quite dangerous.”.........Former new age instructor now Christian.
