I sure do. I've seen some, felt some and been very close to some. Ghost Adventures is no joke. Some of what they do scares the crap out of me. I read somewhere that dogs are very perceptive to them, and if they are staring intently at what looks like nothing, you can crouch down and look between their ears any try to see the ghost. My girl dog barks at nothing all the time...well, not nothing...she barks like she is looking at something and waiting for a response. Sometimes she acts like she get poked or prodded. Everything is energy...that's what we become when we leave the human world...it is how we leave that determines how the energy behaves in the present time.
