When I was really little, i remember I was walking through a church and entered the main room, only to find a vampire praying to a candle that I figured symbolized the devil. The candle was sitting atop a piano/organ or a tall, long wooden table of some sort.
While he was in mid-prayer, I walked up to the candle and extinguished it with something. I can't remember what I used.
The vampire immediately noticed and lifted me up off the ground. In his rage, he sunk his teeth deep into my neck, which is when I woke up.
No idea why I remember that so vividly, I was pretty young at the time and I'm pretty sure it only happened once.
Also, when I was a kid, I remember right before any nightmare occurred, a near-blinding, "sharp" (for lack of a better word), sparking point of light would start slowly at the end of the hall, then speed up in a spiral motion and travel down a long hallway toward me. The nightmare would start just as the point of light smashed into my face. The only way to not have a nightmare was to try and wake up before the light hit me. Eventually it just stopped happening.
I also dreamed last night (nope it was actually this afternoon because I napped) that I was in a freak accident and had much of my skin destroyed somehow (probably burns or tears, not part of the dream anyway) and I was near death. The dream started after all these events, as they were like memories or something.
Anyway, after I was dehospitalized, everything seemed mostly normal until I noticed my friends were acting differently around me. I looked into a mirror and realized for some reason I was black. I had all the same facial features, but my skin was black for some reason. I never really found out why, but I continued to do stuff for the remainder of the dream. I think at some point I was at a camp and was forced to move out of my tent for guess-why reasons, even though I was in the tent alone.
Also, when I dream and a person I know is featured in it, for some reason if I know them well and I recall the dream later, the person is not actually there, but instead something to the likeness of their essence or personality is there. I don't really notice this during the dream, generally, but if I recall it later I notice that, if I repicture a scene from the dream, they are not there but instead some sort of essence of them that tells my brain "this is this person" appears. If I don't know the person very well, their literal form will be present.
