I've seen all of them with varying degrees of frequency.

Dominique used to play in the dogs' water bucket. She tipped it several times a day, every day! We learned not to leave a drop of water in there or she'd have it all over the house. Since her death, that bucket occasionally falls over for no apparent reason. It sits on a perfectly flat floor and no critters are near it to knock it over. Even my husband says Hi to Dom every time he rights the bucket.

I often see Twicket lounging in one of his favorite spots. I used to think it was just Kasha I was seeing since they are both big, white cats, but Kasha doesn't sleep in the same spots Twicket did. She usually in another room when I see him. Occasionally, just before I fully wake up, I can feel him on my pillow. He always slept wrapped around my head at night.

I have a Rainbow Bridge dog, Hoodoo, who has visited occasionally too. About six months after his death, I was sitting outside reading when I saw a black and white husky run up the driveway, jump over a pile of logs and disappear into the trees. I actually said "Hoodoo, what are you doing out there?" before I remembered he was gone. I went and checked for a stray dog and there was no husky in sight. I believe with all my heart that it was Hoodoo letting me know that he was ok again. Hoodoo's death was very sudden and completely unexpected. He went from a healthy four year old dog to dead in under an hour. He had a massive stroke for no apparent reason. I really struggled with Hoodoo's death and I believe that visit was his way of letting me know he was still around and still his goofy, happy self. Hoodoo's harness is tied to my dogsled. He forever runs with us in spirit. I've never seen him again, but sometimes when I'm running his favorite trail, I can feel him trotting along with his teammates.
