And as mentioned above, many of us have entertained angles unaware. Jesus in his resurrected body was of flesh and bone, yet he was able to "disappear" like the angels. I personally believe that Jesus and the angels are simply not limited to the three spatial dimensions that we humans are limited to. But that is a discussion for another thread.
Ask yourself what happened to the spirits of the nephalim after they died? They were not angels, they were the unholy offspring of angels and humans. So where do their spirits go when they die? I think the demons prominently displayed in the NT are the spirits of the Nephilim, and the reason they yearn for bodies is because their bodies are dead, unlike the angels who don't die and lose their bodies.
