Ghosts vs. Spirits

I'm a supporter of John Edward, Lisa Williams and other legit mediums. I have had readings by a few that were amazing. I can promise you that there is no way any of my experiences were make believe. I know the spirits or energies of my loved ones were there and were communicating with us.

I'm also intrigued by the television show "Ghost Hunters" on SciFi. I can't stand being spooked, which is how the show is edited, to spook you. But, I do like seeing them get scientific evidence of the existence of some sort of energy.

What my problem is, is that I have a hard time reconciling the two situations in my mind. When I see a medium, I feel happy, comfortable, elated, and eager. When I think of "ghosts" I feel spooked. Yet, is there really any difference between the two situations? I have thought about the fact that maybe I'm not spooked by the medium experience because the energies there are familiar to me. But, I do get spooked when I think of my dad or my brother, both deceased, showing up in my house. Is it that having a medium around is like having support? Or a guide? Someone to tell me who's there? I don't know. I have had incidents where I know my dad and sometimes my brother are letting me know they are around. That doesn't spook me. Just the thought of seeing them or feeling them does.

Maybe I've just seen too many horror movies.
