There are many unanswered questions about why some experiences are more tactile/sensuous than others. The tactile ones do seem to make a stronger impression.
I was reminded of that when I went to a book signing for a book I mentioned on another thread
http://afterlife-knowledge.com/cgi-bin/yabb/YaBB.cgi?num=1281547669that I plan to comment on sometime.
This particular audience tended towards the senior set and focused on the author's hospice experiences, not exactly a surprise. The author invited peopel to share their own experiences of encounters with newly-passed over loved ones. Some did, and it was obviously an act of bravery for soem to speak as the cultural taboo against this sort of thing was strong for them. Some of the experiences included touch or hugs, and that certainly made them more "real" for the people involved.
So why are some experiences tactile/sensuous and others not?
Of course, with dogs, its all sensuous. I could tell my dogs apart by their distinct odors. What is more sensuous than barking-wet-dog-shaking-off (unless it is one that just chased off a skunk)?
