you were having the beginning of an astral projection. NOT aliens.
trust me.. when i was younger I trained my body to do this.

in very tired states, we will be :awake: during the shift.. which happens everynight.. at various levels.

dont be scared. its natural. but uncomfortable.
we think its wierd because our society model at present says so.

go to astraldynamics.com

when i foudn this site - over 11 years ago, it was not like this. just a lone man- robert bruce- who made his own manual on how to have OBE (out of body experiences) on the astral plane. and remember them
i trained myself for over a year.. near the end i started getting what you experienced, quite regularly. even when i didnt want it.

anyways, read up.. you MIGHT run into strange/scary voices, things after the vibrations ..
they are low level negs that like blowfish, will puff up to scare you- they feed off low level energy like fear and hate.

go with god in mind. go with angels in mind. asdk archangel michael for protection. imagine yourself in a tube of white divine light before you go to bed.

ive had archangel michael intercede on my behalf when I met one of the negs- i felt a burning fire throughout my body as I was paralyzed and looking into the face of some negative energy being.. as the fire passed- I was able to move again and felt a sudden peace..

just my two cents from personal experience.

good luck and love to you
