Science and metaphysics have a stormy relationship at best. They have long been at odds with people on the metaphysics end of things fighting over whether their experiences are valid and the scientific community solidly arguing against the possibility of many of the experiences that the other side have had. It is my personal belief that, in time, science will be able to prove the experiences of those that are more on the mystical side of things. There is scientific proof of haunting, we just have yet to find it yet. Both sides need to meet in the middle and acknowledge that there are many times where experiences are simply flights of fantasy, but there are also many times where things re quite real and we simply do not have the tools to yet prove it.
