That's something I used to do a lot. As a kid, obviously I tried to get inside every empty house I found, especially those in the countryside. I tried to guess how it looked like before I went inside and then imagined people living there before everything was broken, dirty and abandoned. It also gives a perception of time. Some very good houses, way better than new ones, are now empty and falling apart. Families were formed there, somebody grew up there, people were happy there.
