This actually happens to me a few times a year. More since I have been pregnant. Our dreams are more vivid and emotions are stronger when pregnant . If you are into dream interpretation it might help you in your waking life to help process something or even bring something to your attention that is on your mind that you are unaware of. If not just remember how emotional we can be for no reason anyway lol
Yes accept I had a dream about a past experience/trauma that happened to me in real life and dreamt it was happening again and got triggered
