Multiplicity

Personally, I don't get the feeling of being that person, I just have the feeling of remembering things from their point of view. The only time I get the feeling of being another person is when I am about ready to merge with that particular person. As far as the use of those memories, I think it still influences how I use them because often, feeling something from someone else's point of view is kind of like "walking a mile in their shoes" and it affects how I think about things and what my opinion may be.
Hope this helps
