Redcap is a rather unpleasant fellow who lurks in ruined towers and castles, especially if they have a wicked history. It’s said that Redcap kills travelers who wander into his ruined home, using the blood of his victims to dye his cap.
Redcap holds a particularly creepy place in my heart, mainly because I saw something very similar as a young child, long before I ever heard of such a creature. I was sleeping in my mother’s bed and in the doorway I saw the silhouette of a man. His form was darkened (from the light behind him in the hallway), but he had a red cap on. I closed my eyes, and when I looked back, he was closer. Each time I hid my eyes and then looked, he was always closer. Until I hid my eyes and never looked again. Morning came and I wasn’t dead. Rejoice!
What’s more is that my other siblings said they saw him too, at different times, and in a similar fashion (in our mother’s room, his features darkened except for the cap). Unless, of course, they’ve just been messing with me all this time (highly possible).
