The last two times my wife & I went house hunting, she commented she gets exhausted having to experience other people's energy...after looking at countless older homes with 'character' and needed repairs, we gave up and moved into a builder's/realtor's spec house (no previous residents!). We both picked up on something/someone particularly unpleasant in a couple homes.
...Along the lines of the belief in a camera taking (some of) someone's soul, maybe a little visual 'echo' remains in the camera...if you subscribe to camera metaphysics rather than just plain physics. I've heard people comment similarly about musical instruments, but I don't think I agree. I'm still thinking about a Pinata camera...someday....just keep the kids with broom handles away. Murray
