What is the meaning in a dream of barn

Went to my grandpa's barn to look around and aliens show up

I was in a barn. It was dimly lit. I was at an open stall door, watching a newborn foal sleep. The mare was in the far corner, also dozing. She was a dark brown. The foal was blonde.

I'm walking along an entry road leading to a large graveled drive of a disused farm. The main house appears to be in good condition unlike the nearby wooden barn which is in such disrepair that the horizontal beams forming the walls have deteriorated and fallen apart leaving big holes. As I'm standing on the doorstep of the main building I look over my right shoulder to find my ever positive friend applying a new coat of wood protection despite the condition of the barn itself. I see her efforts as wasted as she'd need to rebuild the barn anyway. Behind the barn is a small bare earth area with three cages used as animal pens. Their size resembles the fit of a person standing up although not quite tall enough. Their doors are left open and the flooring is covered by a soft layer of straw. Realizing I'm walking barefoot and the straw looking warm and soft I consider stepping inside one but change my mind upon seeing small pellets of animal excrement inside.
