supernatural superstition bunk
tetrapod;
I can see you feel strongly about this but it's a little harsh, obviously you havn't had anything unexplainable happen to you. Others have. Seeing a health professional may be a good idea - but if it's real then you just distroy the childs trust in adults - there a good start to life some shrink twelling your parents that the kid has a altered sense of reality and should be on some nice little calming drug [and visit them regualrly of couser for the rest of their natural lives].
My wife and I have experienced strange stuff in the Philippines that had no rational explantion. It was spooky as and despite not wanting to beleive I had to open myself to the idea of there being more than I or documented science could explain. Which doesn't mean it won't be explained in the future - but certainly not by closed minded "educated" health professionals with a motive to maintain their own practices.
In our 1959 house we have had some strange things happen - but apart from 1 incident this year it has only been my wife and notice them. It's a little hard to dispell hearing what you assume are the running footstep of your kids playing way past their bed time, hearing the step dissapear round the corner, see no one there and then look in their room to see your kids are SOUND ASLEEP in BED. The incident this year was in the Kitchen after school, my kids were having an snack at the table, I was standing at the sink - we all saw the kitchen door go from full open to slammed shut hard enough to shake the house. No windows open, no draft until the door slammed. Was this collective insanity? My kids looked at me dumb founded - who did that? I suggested the wind, neither was buying it.
So I don't know about encouraging it, but keep an open mind.
