I do! It has gotten much better over the years, but I couldn't sleep without a night light until high school because of it. Even now, I still whip it out if I get especially anxious. My problem was that even before I can remember, I was apparently seeing red eyes everywhere in the dark. I was terrified of things coming to hurt me, even at a young age. As I grew older, I started having very violent nightmares - bad enough that I would wake up screaming and not tell my parents why. And when the lights went off, all I could think of were these intense, brutal images in my head of something lurking in the shadows and coming to get me. (I'm trying not to be too detailed here so I don't frighten anyone.) It didn't help that I have believed for a long time that there is a being in my house and I didn't know what it wanted. Honestly, the thing that ultimately helped was self-conducted CBIT. I set up controlled environments where I would be in the dark, practiced deep breathing, and showed myself that nothing was going to hurt me. Also, I came to realize that the being in my house is actually just trying to prank me and didn't understand how sensitive I am until recently. It's hard being 21 years old and afraid of the dark. But it's getting better. I just wish I could adequately explain to people why I am so scared. The images that come up... They're horrifying.
