Is it normal to have visions???????????????????

It may sound crazy but it is not because im afraid or anything but usually every time some one gets hurt or i see some one hurt i imagine it as if it was me but not see me physically. its as if i can see it happening. i see the damage being done from the inside. its not that i feel it but understand how it hurts and can feel my nerves from where ever it is i imagine it hurt tingle. I get goosebumps right after. for example when i went to the hospital because my uncle was getting heart surgery and when i saw all those scars left on him i can see it happening through a many views and also as if it was me getting the surgery. while i was walking around the hospital to calm down reading all these a R.I.P to people who died and seeing all these rooms with people in them i felt the pain and my head went crazy just imagining all the the pain and all surgeries that have and were accruing at that time. i can also see things rewind but im not sure. I can control this but i like doing it because i like experiencing it and learning from it. I guess its just that i have a big imagination because when i was a boy and still now i can look at objects and imagine how it was made kinda crazy but i think its awesome.
