Ok, so both of these nightmares revolved around something/one trying to kill me.
The first dream was of me and my wife (for no apparent reason) keeping a mama bear and cub, in our house caged. They get free, and the mama bear starts attacking me, at which point I spent most of the dream wrestling this bear as it tried to kill me. I grabbed a knife in an attempt to use it as a weapon, but it was less then functional. A folding knife that wouldn't stay open as it's lock was broken. This made me cut myself in the knife.
I eventually managed to kill the bear with brute strength, and woke up shortly after the neighbors came to investigate what all the fuss was about.
The second dream. I was on. A college campus, I'm a assuming my current one. And I ran into what appeared to be a crazy and sadist security guard. He partially attacked me due to me overhearing him talking about hurting people to himself. I get away and go to class, where he shows up to threaten me. He begins to verbally assault me, and I physically attack him. We then fight on 3-4 seperate occasions, where each time it seemed like he was dead/incapacitated, but he'd show up the next day, and continue attacking me as before, although now he had some handicap, arm braces, scars, etc. I eventually succeed beating the **** out of him, with help from some classmates, and even my professor. The dream ends with me being investigated for his murder (as we through him off a three story balcony).
These aren't normal dreams of mine. I usually have goofy interactive dreams. But these are out there even for me.
