Best thing is an EVP
Take a look at some of the ghost pics on google, take a look at ghost videos on youtube and listen to some of the spooky evp redordings on youtube. evp are noises recorded that are made by ghosts as evidence of the paranormal.
It is a ghost voice you get from a digital recorder. It usually sounds like people talking in Static on the radio.
In order to talk to a ghost you have to be able to hear them. I guess you can talk to one without being able to hear it, the hgost can give you signs but then you can only ask yes or no questions maybe a little more. When you talk to a ghost remember that the ghost was maybe a human before so talk to them like they are, strat with hi and ask thier name.
You can find EVP samples by typing in any search engine (VP samples) There are numerous sites that offer sound snippets of what are proclaimed to be spirit of ghost voices. One such site is www.ghostlyvoices.net. Weather the voices are ghosts or not is a subject much debate and disagreement.
Talk to the ghost any way you want to; it won't complain.
Unknown. You may be able to talk to a ghost, but this is not verified.
