Thread: Abrubt Plot Changes

Have you ever been observing your dreams thinking you're following a solid plot when all of a sudden it changes ?
A recent dream of mine had me following a studious gentleman with me playing the role of his close and trusted servant assigned to carrying his suitcases. I was following him into a restaurant along with two others behind me who I will assume were his close friends and associates and all of sudden he takes a right turn away from the restaurant entrance and transforms into a completely different person. The scenery and the appearance of the surface I was traveling on changed as I made the right turn along with the character. The rest of the dream then took place at this different character's residence with me taking on the role of a guest but I can't be sure whether or not the plot changed again as the dream progressed.
Why does this happen ?
Oh and I wanted to post this thread into the General Dreaming Section but I mistakenly posted it into this section, if a mod could fix that for me I'd appreciate it !
