Ezekiel tells of someone seeing the four cherubs. John Klein and Adam Spears writes of them along with angels, demons, devils, and nephilim. They have spent years of evenings together gathering information about such as these and writes about it.Ezekiel 1?
Although the flood wiped out the Nephilim, they were related to the angels who can take on human form. The giant that David killed probably was a Nephim, we may have some in our world today.
I am sure that if we could be aware of all that is going on in our world that we would be amazed. I had the wonderful experience of becoming aware of beings other than the ones we sense usually twice, once during a birth and once during a death.
I am fascinated when scripture tells of times humans were made aware of beings in our world like Elisha seeing a mountain full of beings when God opened his eyes.
Adam and John say that fire is often mentioned in connection with these beings.
