Nightmares...Ghosts...Demons?

Dreams are always hard to decipher because every dream is specifically concocted for that individual. If you were suspicious then that is most likely what your subconscious was trying to enlighten you of. The dog can symbolize many things: a fear of yours, symbolic of a close connection to someone else, etc. The hood can mean a shroud around information you're supposed to discover, or a threatening person trying to keep their identity/behaviors secret, etc. The fact that the being grabbed you can show some sort of danger, or harm. It really all depends on the environment of your life.

Well the woman means temptation and guilt, the dog means inner conflict with yourself, and the hood means your hiding from from a person or situation. What you see when looking out the window is your outlook on life. Her coming and grabbing you means you feel the need to defend yourself, and you feel stressed, vulnerable and hopeless.

Sounds like a nice dream.
