Yeah there is supposedly like 10 dimensions to our reality and the E.T.'s/UFO's work on the 4th and 5th dimension which is why all that missing time and other high strangeness occurs during abduction. It is like us in 3D going in a 2D world. The beings in 2D would only see a flat, cross section of us as 3D beings. Pretty wild stuff. Inter-dimensional Universe by Philip Imbrogno is a good book to read on it.
