Dreaming of crying but there's no sadness?

i had a dream last night i was in a house with 3 guys i didn't know them but in my dream i felt a knew them all my life, we talked like old friends who hadn't seen each other in forever (i'm female btw) anyway in the corner of one of the rooms in the house i saw 3 kids my step kids, they didn't feel like i knew them at all. when i enter the next room in the house, which i knew well (but i've never seen it in my life) i was on a stage, i quicky took a seat in the first row and watched the very short play. i felt like the only one there but i looked around a few rows were full of people, i dind't stay long in went out a diffrent door and ended up in the living room with a man one of the guys from before and he looked at me and said, "why are you still crying? youve been crying this whole time." but i hadn't felt sad in my dream, i woke up short after that with puffy red eyes and a running noce as if i had been crying for hours.
