People have such weird experiences, that they are often not believed or ridiculed when they mention the strange happening. So they keep quiet and never tell their story (again) to anyone. With the internet now, many people come out of the closet and can safely tell their story under a pseudonym at social media platforms. It is not uncommon to encounter a strange (humanoid) being in the woods. They seem to live or hang out in woody areas, although some do venture into our back yards. It is far less uncommon to encounter an unusual being at seashores. In my article of Oceanic Humanoids several of the stories are of strange beings coming out of the water at the sea shore. Personally I feel that these beings are not physically as we are. They are dimensional beings, who normally reside in another dimension, on Earth, but they can temporarily make themselves visible to us, or even attain some physicality when entering our physical dimension. These beings might have a habitual form, but when they show themselves to us they can take any form they want. So sometimes, they appear to us in a very unusual form, often in humanoid but also in animal form, or a combination of both.
I just found a Reddit post of someone who was witness to a real strange encounter. He was hanging out with friends on a beach at night when a man in old diving suit walked by, with a lantern in his hand. It has all the characteristics of a dimensional being showing itself in a particular form. Go to my article of Oceanic Humanoids to read the story and my interpretation of it.
