Hi there I had a weird dream i'm not quite sure if it was a nightmare but I was in a church (inside) and I ask a security guard about my grandma (who passed away 4 years ago) and they show me her tomb after that I saw a giant wooden door I enter to that door and I saw an old man wearing something red his mouth was wide open I got scare and I ran away some people were following behind me calling me my name.
Hello there! Could this possibly be a dream about being afraid of your past? Perhaps you have to face whatever is behind that door in order to move on. It seems there are other people calling your name who wish for you to do the same.
Just my two cents. I hope this helps!
