Is The Forest haunted?

Few years ago I thought my game glitched out or something while exploring the shores in peaceful mode. I saw a man standing on a boulder. It was very creepy as he was so far away that the shadows made him look like he didn't have any features. As if he was a "Shadow person."

Honestly i thought it was a creepy glitch. Ive seen MANY weird things in the game. So today I decided to return to the game and play in VR and I made it back to the shores and saw the boat full of loot waiting for me. But I saw something i have never seen before. A man. He was standing on the front part of the boat staring at me. This time I could see him just a little better. Red shirt and a backpack. Another survivor? As soon as i got closer he began crouching down and entered the boat. Strangely where he entered the boat from had no real entrance. He was passed the stairs. There was a small trap door thing but that was directly on top of the location of the bed. Inside the boat was a severed head and a lot of loot and a locked door. Dunno if he was hiding in there but again he entered the boat from somewhere where there was no entrance.

So are there secret Survivors in the game or maybe ghosts? Keep in mind when I say ghosts I mean in-world ghosts that the devs put in the game. Not "OMG my game is haunted" ghosts of course. Or is this just a weird glitch?
