Before man could communicate without using their mouth. For people who read the Bible, that was the esoteric meaning of the Tower of Babel. Human used ''telepathic thoughts'' to communicate. That fake God who confounded their language was not the real God. Each curse addressed to men was in fact a lost of a spiritual ability. Dreaming of doing something is in fact a forgotten knowledge. You can't imagine something that is impossible, for every thought are possible. The only problem is to realize it. The flesh or the body is a trap for the soul. What you call dream is in fact the real world. That is why you can do incredible things in your dream. In the dream your soul is not limited by the flesh. The first curse addressed to Adam and Eve was the entrapment of the soul in the flesh. Remember Jesus said flesh and blood can not inherited the Kingdom of God. So the question is knowing that, why someone would put our soul in the body? Human are fallen angels trapped in physical body. Hence the reason why you want to fly, to talk telepathically because you had the ability to do those things. You have already existed on another plane of existence. That is why some of you have what you call flashback and deja-vu. You can't go to heaven unless you were from heaven. Revelation 3:12. a lot of verses of the bible are written in parables.
