I had two experiences since my brother-in-law was murdered in November, 2010. Both are related to him. He was 20 years old and very close to my son and my husband.
On Christmas Day, my husband was very upset and depressed from losing his brother three weeks prior. He was also there and watched him die, holding him, trying to keep him from bleeding out. Every day he has flashbacks about the whole thing and is still very stressed out and fragile.
That night, when everyone went to sleep, I prayed and prayed that I could get a sign to let me know that my son and my husband would get through this, that everything would be okay and that he was watching over us and protecting him from the bad things that got him killed.
I stopped praying and decided to turn my light off, and as soon as I sat down in my bed I heard something. We have a gold wreath about six inches in diameter with bells on it hanging in the kitchen, which is about 15 feet away from my bedroom. I heard three distinct shakes from it. I sat up in bed and listened for it again, and this time it was loud like it was right next to my door. I got up and went to go look in the kitchen and it was rocking back and forth.
It was the middle of winter, so all the windows were closed -- there was no breeze. I think it was him giving me a sign.
