Wraith (Apparition & Initiation)

I will leave this experience posted here because I need to know if there is someone with more knowledge, who can explain to me what type of entity (and what is its name or classification) in order to understand what exactly is this spiritual experience:

I appeared at my family home in Puerto Rico, and there was no one there. I exited from the kitchen area and was walking down the main hallway when a paint container or something similar that was placed on the floor of this hallway moved just in front of me, and it quickly crawled across the floor until it entered the nearest room.

I ran after the object, and I stood under the door frame of this room, and there I saw how the container continued to move to the right rear corner of this particular room.

That's when I started asking for whatever it was to manifest because I couldn't see it. And I asked saying: "Please, whatever it is, let me see you!"

There was a moment of silence, and in front of me, on my left side, a kind of semi-transparent specter materialized.

The wraith was floating a short distance from the ground about two feet (0.61 meters).

He was skinny and his neck was crooked almost like an "S" leaning to the left side with his head almost resting on his left shoulder.

He was also not human, although he had 2 legs and 2 arms quite normal in proportion to his body. But his ears were a bit pointy and he was bald, his face was misshapen. His skin was quite yellow like a chicken and was wrinkled.

He had on tight gray or dark blue shorts that reached to his knees. I think he had nothing else on, neither shoes nor shirt.

The wraith put me lying on the right side of my body, and I was seeing that the whole room was partially blurred... I understood that I was with the specter in a near dimension, and that's why I could still see the room, but now from his own dimension where this wraith lives.

I also realized that I was paralyzed while lying on the right side of my body, and that I could only move my eyes.

Although I was talking with the wraith for a long time... I don't know if I was moving my mouth or if I was communicating through thoughts. But the wraith answered what I asked about his presence in that place. I told him: "Why are you here?" And he responded by saying that in that place there was a kind of monument or foundation (at that moment I could see in my mind's eye a rectangular stone cover on the ground with a hole in the center). Apparently, that was the object that kept the wraith in that place. I also asked him since when he was there, and he told me that he had been in that place for 7,000 years.

After talking a while longer, the wraith told me that he was now going to initiate me... Immediately afterwards, the wraith pounced on me, and buried two fangs in the left side of my neck. This really surprised me, because I didn't expected that the biting of the neck could happen in real life! But when he sank his fangs into me, it didn't hurt, but rather felt like he was pulling for a moment blood or energy.

After it was over, I saw the specter kind of sat down, and he looked calmer.

I never felt fear at all, and when I woke up, I didn't remember anything until the next night at 8:08 pm when I began to remember all of this experience which happened on May 3rd, 2023.

The mythologies of wraiths are found throughout several different cultures actually, however they are not always the same type of being or represented under a similar light. Some deeper paranormal investigation is often required to solve, identify or liberate those entities, at least those that require such since for others that is simply their nature and any form of liberation would turn out to be insulting to them.

So this situation is somewhat complicated?
