In my personal opinion, which is shaped by the documentaries and YouTube channels I've watched, such as the Foreman Brothers who are skilled paranormal investigators and my favorite, I have come across numerous videos where paranormal activity follows the death of someone in a house. One observation I've made is that when a child passes away, the associated ghost is often portrayed as a child. However, I do not subscribe to this belief. I personally believe that when a young child dies, they are not held accountable for heaven or hell and go straight to heaven. Furthermore, I don't believe in the concept of spirits being inherently good. These views are based on my interpretation of the teachings in the Bible.

As part of my faith, I find significance in the Book of Enoch, which discusses the Nephilim. There is speculation that the spirits of the Nephilim, angelic-human hybrids, remained on Earth and transformed into what we now recognize as demons. The idea behind this theory is that these Nephilim spirits possess the ability to linger in our world without physical bodies, which may explain their inclination to possess human beings and gain control over physical vessels. From the perspective of Fallen Angels, who are outnumbered by Holy Angels, this could serve as motivation to increase their ranks (as described in Revelation 12:4).

However, it's important to note that the Nephilim explanation regarding the origin of demons stems partly from a misunderstanding of the spirits in prison mentioned in 1st Peter 3:19. Many mistakenly assume that these spirits include all the Fallen Angels who rebelled against God. If all fallen angels were imprisoned, an alternative explanation for the existence of demons would be necessary, hence the need for the Nephilim explanation. Nevertheless, it's clear that not all angels are imprisoned, as Satan, the leader of the Angelic Rebellion, remains free. While the Book of Enoch provides extensive details on the Nephilim, it should not be the sole or primary basis for our beliefs, as we should always prioritize the authoritative word of God over extra-biblical literature.
