having a horrible thing like a ghost in the slab near the air conditioner
Dreams about ghosts can often symbolize fear, anxiety, or unresolved emotions in one's subconscious. The ghost being near the air conditioner could suggest that these feelings are being triggered or exacerbated by something in your waking life that provides comfort or relief, but is also possibly contributing to the negative emotions. It may be helpful to explore what may be causing you distress and how you can address and process those feelings in order to find peace of mind.
