dreams

Big question may seem absurd but I have to ask. I keep dreaming that my sister fooled around with ex bf which I have two kids with 😒 I know it's not normal but this dream keeps coming back all the time and I dont know why. My sisters bf was in prison at one point. And when he got released he came to me accusing me of knowing that my oldest sister had a thing for my kids dad I didn't know what he was talking about. Could this have to do with why I keep dreaming about that? And no my kids dad didn't fool around with my sister in real life and before people start asking how I know that I can say I know that for a fact because my boyfriend was never with my sister alone ever just when I was taking a piss in the bathroom at my sisters other then that never . He worked with me and he was with me 24/7. We had the same friends and everything. Only time he wasn't with me is when I told him to go have a boys night in which I'd go have a girls night but in the end we would end up together because my friends were dating my boyfriends friends. And my kids dad didn't have a phone of his own we shared a phone. And yes I trusted my bf we just couldn't afford both our phones so we decided to use only one and we lived together.
