I wouldn't be able to even guess how many, but then there is always room for more. What we experience after we die, at least at first, during any transition, may have a lot to do with our theory of "what happens after death" that we held when we were alive. What we experience in life is very much colored by our beliefs, so perhaps also is our experience at the end. Sometimes when I have finished binge reading a really good book, or binge watching a streamed TV series, I notice that for a while, I view "reality" a bit differently. As if something of the viewpoint or color of the story gets carried over into my everyday waking life for a brief time and I might even see things as the protagonist might have. We are what we eat and its easy to gain a few pounds that can take a while to lose.
