I had another weird dream if anyone can analise this one!?

Ok a little background info first, my mum and my sister-in-law (Lindsay) do not get on ever since they had an argument last boxing day and Lindsay threw my mum out of their house and made her go home! My brother (Matt) still comes to see mum but neither him or Lindsay speak to my sister anymore after another falling out around last christmas. So here's my dream:

Mum was sat in the middle of the settee in our lounge and Matt was in the kitchen making drinks. Me and my partner were just in the lounge stood there. Then Lindsay (she hasn't been to our house since the fall out) came in and we heard her talking to Matt in kitchen and we were like oh no! Then she came in an looked at mum (I was thinking what's she going to say) and she said i put a roast in the oven before i came and mum just went mmmmm, then Lindsay went to sit down next to mum and mum went to move up but then all of a sudden Lindsay sat on mum's knee then mum shoved lindsay's legs up to get her off and lindsay ended up like rolling over backwards and there was a little struggle between the 2 of them before Lindsay fell off the settee and we thought there was gonna be a right fight then Lindsay just started laughing then i woke up.
