The first thing people want to know is how does astral projection happen? Clearly, it’s not something common that people experience all the time, so what triggers astral projection?
Astral projection and OBEs are very interesting to scientists, but the phenomenon leaves neuroscientist puzzled. Medical professionals don’t dismiss this experience anymore, however, they describe OBEs as a result of neurological or brain dysfunction. No doctor or scientist was able to pinpoint what exactly triggers astral projections.
There are stories people who had near-death events tell; they usually say how they were floating above their body in a hospital room and observing medical staff while they were trying to revive them. This would be a perfect example of an involuntary OBE and these can be caused by a range of factors including illness, trauma, and even food or water deprivation.
There are also intentional OBEs which are achieved by lucid dreaming and intentional astral projecting. How does this work? Have you ever dreamed of flying or being in the sky and you felt amazing? If so, then you’ve had a lucid dream (which you weren’t aware of) and an OBE!
