Well not a classic alien like in scifi pictures. But Ive taken spiritual trips to the fourth plateau and beyond and met God or the embodiment of a higher being. Also I met what could be called aliens. That was in the frequency realm, like how light behaves as both a wave and a particle there is the duality there as there is with this universe. We are of the particle world and the aliens are of the wave world, I have travelled there and they are very curious and friendly. Much higher intelligence than us. They are responsible for all spiritual experiences and religious teachings.
Cool.
You called them intelligences.
You believe there are multiple distinct intelligences.
Importantly, is it one intelligence in multifarious forms, or distinct intelligences living in a common abode?
