Hello sandlmull and welcome!
Well, those are two different types of hauntings. The 'play back like a movie' one is a residual haunting; the other is 'interractive' or 'intelligent', when the ghost is able to interract with us in our environment.
I think that either kind can be someone related to you, but not always. Ghosts aren't necessarily people we knew in life.
