I think I witnessed the transition from sleeping into a dream?

Let me first say I'm a very active dreamer and 8/10 dreams I will have control of myself. So I was having lucid dream and for the first time, I controlled my blinking in the dream and kept blinking to see something clearer. All of a sudden I started blinking in real life I could tell because I could see what was in front of my real life face) and opening my eyes and it pulled me out of the dream, yet I was still sleeping (I could only see darkness and could move, but didn't because I wanted to continue the dream) so I told myself "you're still dreaming" and It seemed as though I witnessed the transition into my next dream, which everything got grey and blurry and twisted like going through a portal in Minecraft or Destiny, it was kind of disturbing. It brought me to a dream where there was a news broadcast, and I didn't want that so I told myself "I'm in the Forrest" and the blurry static changed my dream to a forest, but not for long because I was disturbed from witnessing the dream transition I just woke myself up… What does this mean? Why did it happen? Is this a thing? Can someone explain please?

<8/10 dreams I will have control of myself> I'm envious. Lucid dreaming is only an occasional thing for me.

<Why did it happen? Is this a thing?> Yes, it was a hypnagogic hallucination, actually, and not a dream proper. The difference between dreams and hypnagogic hallucinations is physiological--dreams happen during REM sleep, while hypnagogic events (well, technically, 'hypnopompic' is the term, while we're awakening) happen during the transition periods between being awake and asleep. From a practical point of view, though, they're the same thing as far as I'm concerned--we're experiencing visions in either one. So, what you were experiencing was a hypnagogic hallucination, which continued through the waking process. Which can be pretty interesting when it happens, as you now know.

<What does this mean?> It doesn't mean anything--it was just a dream.

Hypnagogia is why most 'ghost sightings' happen at night and in the bedroom--because they aren't paranormal at all, but are sleep and dream related. It's easy to understand why people who don't know this might start to believe in spirits, if they wake up to see some sort of apparition hovering over their bed, only to fade away in a few seconds as they awaken in amazement. What's hard to understand is why so many people cling to the ghost belief even after hypnagogia is explained to them. Or maybe it's not--people have a deep-seated desire to believe in an afterlife, and I suppose thinking they've seen a ghost reinforces that belief for them. It's all just our subconscious imaginations at work, though.
