Recurring dream

I have had a few dreams in the same location, even though I am confident I created it in my head. They always take place in a really old house filled with paintings, with tons and i mean tons of spiders in it. The same image of looking in and seeing a few dozen dead and living spiders hanging from webs has popped up in these dreams every time. This time I had this cool bit where one of the paintings was of a hallway and the main room in UV light and you could see the web structures and paintings all lit up vibrantly
