There's a spirit in my house and I wish to communicate with it...?

Sounds like your family had some bad luck and blamed it on ghosts. However, nothing paranormal has ever been shown to actually exist. And you don't have anything here to make anyone think you've got the first ghost ever. No one has been able to show communicating with ghosts is possible; if it were, we wouldn't need to hold murder trials. Basically you're imagining you've got a ghost, and all the ways of 'communicating' with ghosts are also your imagination (like moving an ouija board - it's all you), so you'd just be piling one superstition onto another. While common, it's not getting you anywhere. It's like praying to Zeus to get rid of the unicorn in the bathroom, then assuming it worked when you don't have a unicorn in the bathroom.
