Yes, my darling dog came back to visit or stayed with me a while after I had to have her put down (she had diabetes and the insulin was no longer effective, she was getting ulcers in her bladder, etc).  I was devastated but the strange thing was that she was so calm and relieved on the day we took her to be put down - like she knew and was glad to be released.  She has come physically to me but mostly in dreams and I would feel her as though she was solid, not ghost like or anything.  Made me think of the bible where Jesus said to touch him and he wasn't like a ghost but was solid.  Makes me wonder if energy can be almost solid even if our physical bodies have expired.  Still, I wish my girl would come back and visit me but I think she stayed  near to make sure I was okay and then when I finally was able to move on more after her death, she was happy to go to the Light permanently.  No more visits from her anymore, sigh.

Yes, but I have one of those hunches that I should say a different experience. Dunno why, but lets go with it.  

There used to be these two really pretty pine trees literally right next to the house. My mother loved them because they were really very pretty, but they also kept the house both warm and cool. They were older than the house, which was odd, but they were still very young. She noticed one day that some branches from those trees were hanging over the house after a storm, and so she agreed with my father that they should be trimmed. It turned out my father had lied to her. He asked for them both to be cut down. After they were, weird things started happening. To make a long story short, these two trees actually began to haunt the house until my father left! I hope they're alright now.

Cheers!
