I felt that frequently after Morris passed. He would always rub against my legs when I was on the computer. I'd feel it, reach down to pet thinking it was Buddy and realize that there was no one around and nothing that could have possibly caused that sensation. I would feel cold air around my legs prior to it.

When I'm really sad and stressed out I have a dream where I step out on the porch and Tiger greets me. It's disconcerting at first, but once I wake up after having "spent some time with him", I feel very at peace.
