The weird things bout me

It is cloudy October and it's kind of my favorite kind of weather. Cloudy, rainy, wet, and dark is kind of my aura to be. Cause with the sun shining so bright I feel like I'm gonna melt or just gonna be burn to ashes like a vampire. Speaking of vampire I think I am one (?) Cause every night I couldn't sleep, and it's the time when I could be fresh, and when I have time for myself hehehe. But I don't know why I do see ghost. Every time I try to run away from it, It doesn't go away. So what am I? I can't sleep at night, I see ghost, and I have a kind of sickness that I don't what it is....
