Dream about Ex boyfriends

So I had a dream last night that I was at work, as a receptionist for a block of flats. A few of my ex boyfriend’s friends arrived and I let them in and they said they were going up to see him as he was having a party. Then more and more turned up, I never saw him in the dream. Then later another ex boyfriends mum arrived and asked to be shown up to his flat to see him for dinner. He was my boyfriend 8 years ago so not sure why him or his mum have come up in my head..
