Hi cheropride -
I do not think you are making this up. You did not mention how old the house is, how long you have lived there - or if your child is a teen.
A few options of what may be going on pop in my head:
If he is younger than a teen - he may well 'see' who is doing this from the other side. He may not have said anything more on the subject so that you wouldn't freak out.
You son (teenaged years?) may be creating (unconsciously) some of the happenings. I had a daughter who (as a teen) levitated things when she got angry - but I always managed to keep this knowledge from her.
When I would get frazzled - tv's, computers, etc (anything electrical) would go absolutely wacky. Both these two examples are uncontrolled metaphysical abilities. It can often happen when a teen is entering or has entered the hormonal stage.
Second thought: Your son may be right about who is trying to get your attention. Sometimes those loved ones who cross over try to get your attention to let you know that they are visiting. You say you never feel fear or evil - could it be a loved one popping in to say "I am here!" :-)
And ignore any who criticize your experiences - unfortunately narrow-mindedness is not a crime.
