I was in bed and spiders started descending from the ceiling.
Dreaming about spiders descending from the ceiling can be a symbol of feeling overwhelmed and trapped in a situation from which you cannot escape. The bed in dreams usually represents a place of comfort and rest, so this can indicate that you are feeling attacked or threatened in your personal space or in a situation you thought was safe. The spiders may also symbolize fear, anxiety, or a hidden danger, which you feel is looming above your head, and you may be struggling to deal with it. This dream may be a sign for you to confront or deal with your fears and anxieties before it becomes too overwhelming for you.
