I am on a hillside watching a soccer game. I notice at the end of the stadium is an old house so I go in. When I get in, I find myself in the bathroom that looks exactly like my grandmother bathroom. As I am looking around, I find myself looking in the mirror when an arm with a cast starts coming around my neck.
The dream seems to be pointing towards a feeling of being trapped or ambushed. Being on a hillside watching a soccer game could represent a feeling of being an observer of something, perhaps a situation or event, rather than actively participating in it. The old house at the end of the stadium could represent the past or memories coming up. The fact that the bathroom looks like your grandmother's bathroom could represent a connection to your family or ancestral roots.
The arm with a cast around your neck could represent a feeling of being restricted, held back, or even controlled in some way. It could also suggest that you are carrying a burden or feeling of being helpless and unable to move forward. Alternatively, the arm with a cast could represent a physical injury or limitation that is causing you discomfort or difficulty.
Overall, this dream may be reflecting some internal struggle or feeling of being trapped, and may be signaling a need for you to take a closer look at what is holding you back in your waking life and find ways to move forward.
