Dying talking with dead?

Keelay
Curious on your thoughts on this. To give you some personal background, my loving and amazing grandmother who was always sharp as a tack has been in the hospital since Mar 24, and turned 75 on Apr 1. There is a laundry list of issues and that list just keeps growing. Its heartbreaking, and depressing, and very hard to focus on anything but think of how I'd feel to be in the hospital at that age getting infections, oxygens, IVs, bruising, catheter (sp?) etc... anyway, she's been saying Daddy a lot. Her father died long before I was born (I'm 31 now) and I'm curious if you believe the dying speaks to the dead. Posting here in CC and there is a lot of debate of ghosts, religions, etc. Anyway, thanks for reading and wondering what the feedback will be.
