I beleive I was contacted, but by whom?

Over the lst few years I have had a few unusual things happent o me personally. Around October of 1997 I was having a quarrel with my wife over the phone. She was in Ventura area and i up here near Fresno. Suddenly a six candle candlabra literally lifted up in the air and flew about five feet across the room and landed in the floor. This was witnessed by my then eight year-old son. When it hit the floor the phone disconnected and quit working for sveral hours. I feel it was an intervention to stop our argument. In December of 1998 I was working alone in a dentists' office. To make a long story short, I was going to commit suicide that night on my way home and a radio came on all by itself (the building had an alarm so I know I was alone, plus I was in the room with the radio)and was playing a very inspirational song that stopped me from doing it. There are much more profound details and I'd be glad to share them if anyone is interested. The last thing was about a year ago when i was looking at a ghost pictures web site and the space bar on the computer suddenly started vibrating up and down very quickly all by itself! I don't know what it all means but I'd like to.
