Before I write my theory there is one thing you must assume and that is we have lived multiple lifetimes. Alright so the fear we feel when we vibrate when we are inducing a LD or an OBE. I believe that when we are really laying on are death bed we feel these exact same vibrations. These vibrations occur when the consciousness of a person is shifting into a different state of awareness. Basically what I am saying is we are ALREADY vibrating already but we don't notice it. When we die what happens is that our vibrations are changing we obviously no longer have a body that is vibrating on the physical level. Our spirit bodies are much higher in vibration than the earth body and we feel this change as we are dying. So now why do we feel the fear when we are inducing a ld or OBE? It is simple really. If you have lived and died multiple times those memories of all those deaths are locked away in your subconscious mind but can still be accessible.

Now then assuming what I said above is true lets say you are trying to lucid dream via WILD. I know vibrations are not necessary in order to do this but lets just assume a first time LD'er felt the vibes and started to become fearful. What I believe is happening is that these vibes the LD'er is feeling is triggering a subconscious memory of the many deaths that LD'er has experienced. The LD'er is subconsciously associating the vibes to dying. I believe this is why people become afraid when they feel these vibrations.

Like my other more recent post I would like to say this is just a theory. I am not saying this is how it is. Feel free to post what you think.
