Among alien humanoids, these water-beings are truly strange. They have been seen both underwater, and walking out of the ocean or going back into the ocean. Where do they come from?
From the stories I have read, there seems to be different kinds of these beings. I can only speculate that some are real water beings, with fish-like appearances that seems to be fully adapted to life in the oceans. Others might well be ethereal beings that reside in a dimension just ‘behind’ our physical world. At times, they can make themselves visible or temporarily make their ethereal bodies dense enough to move around in our physical world. I would mermaids and merman on this category, although I did not take up these stories in this article. Even stranger are those who look totally human. These humans have evolved to a degree that they are able to shift their frequency to such a degree that they are able to move through matter, and thus through water. In that case they might live indeed in the oceans, that is, in a domed city on the floor of the ocean. Some psychics and remote viewers have talked about the existence of those cities. All this is of course speculation, so you have to use your own intuition in figuring out who those beings are.
These stories again show that there is quite a variety of intelligent human or humanoid life on this planet.
