Dead grandmother appeared in my dream with a message?

Sounds like you were just expressing a repressed fear through your dreams. I don'tknow about you, but if I were in your situation...I would worry about something happening while I was gone.....not being able to be there to help if something happend and whatnot! I really wouldn't worry about it. Usually when a loved one who has ped brings you a message, it's in the form of a comfort, like showing you that you will overcome this obstacle. I've never heard of a ped loved one coming through to scare you or make you worry. Hope this all helps
