I would have HAD to go look! I would love to think their spirits can come back and visit us...

What happened to me one night was different than what happened to you because I DID go investigate. I heard talking. I thought it was somebody outside but it kept getting louder and louder. I noticed flickering lights up in my living room and the talking was becoming very loud. I got up to go see what it was and there was my cat, standing on the TV remote.. He had managed to cut it on somehow and step on the vloume and kept pressing.. Now I keep my remote turned upside down.
