Sleep Paralysis and the Fourth Dimension

When your mind wakes up from sleep quicker than your physical body, and you feel someone pushing down on you or "watching" you, it is a Reptilian (or other kind of alien) in the fourth dimension.

If your mind wakes up quicker than your body, then your mind cannot exist in the third dimension because your third-dimensional human body is still asleep. Thus, your mind switches to the fourth dimension and is able to experience fourth-dimensional reality.

Right now, we are in the third dimension. And, when we die here, we go to the fourth dimension (the astral world). The fourth dimension feels just as "real" as this, but the rules (Darkness's rules) are considerably different over there:

"The astral world is a 'place' where beings reside when they are not in the physical. The physical world is a 'place' where the same type of beings reside when they are not in the astral. The astral world is a complex place full of subtle entrapments just like the situation here in this physical world. In one sense it is far more deceptive than the physical dimension" (Amitakh Stanford, "The Spirit World").

Along with humans, the Reptilians also exist in both dimensions.
