Do ghosts only "talk" in dreams?

[wozniack]

About 2 weeks ago, I saw an apparition of someone I recently written a letter to. He was standing about 2 1/2 feet from me but did not say anything. My question is, do ghosts only "talk" in dreams? Same thing with my grandfather. I saw him standing at the foot of my bed 17 years ago, but he just smiled. He was holding his dog who had passed away years prior to his death. I took it as him showing me he was with his pet, and that he was OK.

I thought I read online that someone had a full conversation with a loved who had crossed over and they weren't asleep. I know with EMF detectors you can pick up on words and sounds that we cannot hear. So it's possible that these spirits may be speaking to us though we cannot hear it.

I feel blessed though to be able to see a spirit and communicate with them while I'm asleep. Some people can't do that. I just wish I could talk to them like I do with the living.
