Signs

My fiancee' died in a terrible car wreck on his way to work on Jan 15, 2000. I miss him terribly. I have gone on rather well and I am going to be married soon. My reason for posting is, do spirits usually communicate thru electronics? When he first died my tv and radio would come on all the time by themselves. I even moved three different times and it still happened. It's tapered down tremendously the last year. The other day I was talking to a friend about it and a container of socks in my closet flew out while I was talking about it! Another time I was telling my boyfriend about it and the radio came on while I was telling him about it. I have always wondered if that was his way of saying he was there. When he died we were in a arguing state and that has always bothered me. My last words to him were angry and he died the next morning. We were going thru a very difficult time when he died. Are there any more ways I could communicate or be more certian? Does he have a message for me? One more thing, he came to my cousin in a dream within a month after he died and told her to tell me he loved me. He had only met her once two months before he died. I just find this all so intriguing. Thanks in advance for any thing you have to offer!
