A childhood belief about in my closet

i had finally gotten my own bedroom, had wrested my independence from my horridly tormenting older sister only to have her ruin it for the next few years of my childhood. it went like this:

there were giant sycamore trees outside my bedroom window that, combined with the moonlight, made the exact same errie image on my bedroom wall every night. it shone next to my closet and, eventually, i decided it had the appearance of a man. my sister confirmed the fact. she told me that it was really the ghost of the man who had hung himself in my closet years before we moved into the house. to prove her story she showed me a picture of him from a book of ghost stories. its still errie to me today to think of how much this random picture looked like my "ghost"
