As I was playing with a few toys in the same area at once, I got to thinking... is this dangerous? Can too many toys or certain types of toys set off some kind of bad/electric/other reaction?

I do know that some chargers and toys have a weird magnetic thing going on and some give slight feedback... can this happen to me while I am playing with multiple toys at once?

Has it ever happened to you? What would set it off? Not possible? HELP!
