I dreamed I came home, and there was a man on a ladder. He was fixing a small hole in the wall. Suddenly, There came this turantula out of the hole! I was just walking by and it was stuck to me with a spiderweb! He came to me via his spiderwebthread. I was really scared since I couldn't stop him from coming to me and I am very scared of spiders. What does this mean?

Being stuck in a web can mean feeling like you are stuck in a situation you can't control.

Since you are afraid of spiders, having a large spider appear in the dream might have been your mind's way of using a concrete thing to represent the anxiety you are feeling about something .
