Dream of apartment, crowd

I was in a big apartment. In a huge block of flats. Many rooms, all spacious and full of light. And there were many people in the apartment. I didn't recognise the faces but I somehow knew they were all my relatives. Brothers and sisters of my grandparents, aunts and uncles, some very distant cousins. In the rooms there were also many... pigs. Not those little ones like pets but regular, big, fat pigs. With different colours. Some pinky, some with big dark patches. They were running around, me with them, having lots of fun touching them and stroking. They were very clean and I was playing with them as you normally play with dogs. But at the same time I was thinking that an apartment is not the best place for them and I was a bit afraid they'd make lots of mess there. So, I decided: we need to go outside. Me, all my relatives (lots and lots of people I'd never seen before), all the pigs, an incredible crowd, all together! That wasn't very easy. The apartment was very hight (10th floor, maybe more) and all at once we wanted to take elevators, stairs, any possible ways out. The chaos was impossible! I took the stairs as I didn't want to wait ages for the elevator. At last: all out! It was beautiful outside... Lots of sunshine. Many vivid colours. Summer probably. I didn't know the place at all.
