Popularity is based on people liking something. There is something to do with psychology especially mob mentality. So if a group likes something or someone, usually that person follows. Maybe that person doesn't like it but the feeling of being different is scary to some people. They want to fit in, as for popularity, it is more a group thing. Also, something like tradition. How that happens? I don't know.
Why do some actions in your dreams come to a somewhat reality? Like I was dreaming and something happened and I forgot like what happened but I think I got hit in the chest, and in my dream I could tell my body could feel it.
This leads to two more questions.
Can you die if a hit is too critical if the above thing is true? and if so....
Is that why some people die in their sleep for no reason?
I think this should be booted over to hobbes section =P Just a suggestion.
