I'd like to share with you some of my experiences with what I understand it's called the hypnagogic state - a state of consciousness defined by being the transitional state between wakefulness and sleep.
The first experience happened while I was waking up in the morning one day. While the dream was fading away, I got stuck in what I see people describe as sleep paralysis, but I would say it was more a controlled sleep paralysis if that makes sense. I could've gotten out of it in the sense that I was able to feel my body to some extent and move it if I wanted to, but I was mentally in a state...well hard to define.. I had that feeling I have when I realize I'm in a dream, but I was also aware that I was in the process of waking up. I couldn't see anything, everything was pitch-black, but not like it is when you close you eyes. I had the feeling that I'm in my head, like spatially, but I was simultaneously aware that, in real life,
I'm laying in my bed, about to wake up. My body felt really heavy, and I couldn't feel my arms and legs very much, like someone injected me with an anesthetic. I'd describe it as having TV static inside your limbs. Over the blackness that
I was experiencing, colors started to form, mostly red and orange, like clouds of dust. Then they started to vibrate and become brighter and I could feel my field of vision expand.(like you know, normally you have maximum 180 degree vision, you only see what's in front of you, well I felt like my vision was slowly expanding towards 360 degrees). As these sensations increased in intensity I started to hear a voice talking to me in a language that I couldn't identify. The voice was part human-like, part other-worldly, and it didn't feel like coming from outside, but rather from within, like it was forming inside my mind.(kind of like in Shpongle's album here

I didn't have control over it. It kept repeating 2 or 3 phrases in this alien language that I couldn't understand exactly, but somehow I had an idea what it was all about. It was something about the connection between my world and the entity's world and it was trying to explain to me how to communicate with it. Then the colors turned intro light and I felt like I was being pulled into something. At that point I got scared and woke up and that's how it ended.
I know this forum is mainly dedicated to DMT, but I've actually never tried DMT before. I hope since everyone here is highly evolved spiritually and experienced with altered states of consciousness that I don't sound completely crazy. I don't know a better place to talk about this than here.
