I've never really had any experiences but I've heard plenty from other people. I'll keep an open mind but I'm highly skeptical.
The way I see it is that the human brain is a wonderfully complex organ. If we have a thought that there is something fishy going on or we are fearful, our brain will focus all its energy on finding a threat if it indeed exists and working out how to counter it, otherwise it will prepare us to run away (fight or flight I guess). This focus on identifying a threat leads it to see things it perhaps shouldn't see as a threat or invents something that isn't there.
Our brain also has quite a tremendous capacity to hallucinate. People typically associate hallucinations with drug use, but there's ample evidence that strange noise frequencies, lighting and of course fatigue and other factors can cause all sorts of hallucinations. This and the brains capability to erroneously fill in the gaps as described above could perhaps lead to the sense of the supernatural and even the possibility of seeing ghosts or spirits.
Anyway, that's my take. That likely won't cover every experience and I won't discredit that, however I feel the human brain can very easily fail us and cause us to see, think or feel things that are, in reality, false.
