Hypnagogia Or Astral Projection?

I've been researching a lot on what has been happening to me for many years now. On Wikipedia it is referred to as hypnagogia, which says "The equivalent transition to wakefulness is termed the hypnopompic state. Mental phenomena that occur during this "threshold consciousness" phase include lucid dreaming, hallucinations, out of body experiences and sleep paralysis." I just had another one of these experiences about an hour ago in my bed and I lucid dream as well without trying. Ever since I was little I'd see "spirits" or things that weren't there according to everyone else, but it was never as strong as it is now and it has been progressing for maybe 6 years now (I'm 19).

So not more than an hour ago I was lying in bed trying to get back to sleep when I came into a catatonic state and my body began to vibrate. I started hearing sounds that were not there before and I saw a demon-looking creature lying on my chest staring blankly into my eyes. Normally when this happens (and I'll get to the other examples later) I am instantly filled with a horrible panic and terror. This time I was still afraid but not to the extent I normally am. The thing on me had bronze-gray "skin" and small pointed almost cat-like ears. Its eyes were a dull yellow and didn't blink. Usually they appear evil but this one was looking at me with sad curious eyes. I have been reading about this and also get links to astral projection, which I'm very interested in. This might be the case so in my fear I asked the thing in my mind what I should do next and what's going to happen (regarding astral projection). The thing didn't open its mouth or move but I heard voices everywhere telling me to just lie there very still on my back. I started to stay still and tried to relax and the vibrations became more violent and I freaked again and screamed no in my mind and tried to move my body. I got one of my fingers free and kept squirming until the thing on top of me slowing brought its finger to my face, touched me, and then I was "released" and everything went back to "normal" again.

In the past the things were not so kind. I've had a time where I had the radio on when I was sleeping and it happened suddenly and the music turned to a woman screaming as if being tortured. A shadowy demonic thing appeared at the bottom of my bed and worked its way forward to me laughing with its teeth out. There were lots of screaming and evil laughter and shadowy things flying about. The one from the foot of my bed charged towards me and rammed into my face, and then I could move again and I gasped for breath because I was having trouble breathing then. Sometimes they talk to me and don't do anything evil but they fill me with such terror and have such a menacing presence. At times it's like they want to have sex with me and I give up fighting them and say fine then, but then they just laugh at me. When I ask them what they want they just mock me and laugh. I've heard of an astral plane that is filled with "parasites" such as these and I was wondering if that is the case or if this is something else? Sometimes I begin to feel as if I'm floating above my bed but get afraid and fall back into myself.

A few other things: one time after one demon thing entered my body and I could breath again I bolted up in my bed and instantly began laughing crazily and then it changed suddenly to me bawling my eyes out. I ran out of my room and instantly I stopped crying and felt normal.

Also, people have told me that they can sense negative energies around me. One random person came to me and gave me a crystal for protection and said they felt I needed it. My sister's boyfriend's friend told my sister that after I stayed with them for a few days he could feel negative energy around me and sense evil spirits and that I should be careful.

I want to continue to attempt to astral project and learn about it, but every time I try (or even if I don't try or even if I begin reading about it again) these sort of things happen. If anyone has any advice or if this is normal please give me some advice! Other astral projectors have said it is terrifying as well. Am I in danger? Am I feeding into my imagination?
