What are recurring dream dreams about?

Like many people I had the recurring dream of being chased by a dark figure, it was a shadow in a trench coat, no facial features just shadow. I began having the dream when I was in elementary school and had it until just less than a year ago. It always went the same, I was running through my house, or my high school or my hometown and he was always right behind, the dream would either end with me falling off a building or bridge or him getting right up to me and reaching out with a shadowy claw and me waking up screaming.

Well I reached a low point in my life, had broken up with my girlfriend and just had a lot going on at work and school. I was fed up with life in general (NOT suicidal, just to the point I had very few "F's" left to give). Had an especially bad day and went to bed, the "dark figure" dream started, but instead of being terrified as I always had been before, I just got fighting mad. I was done with it! If he was going to kill me then so be it, but I was going to give him one hell of a fight! I remembering turning toward him and charging full bore right into him, all fear was gone there was only utter rage, I wanted to rip him limb from limb. I had the general dream sensation of wrestling around...and realized I wasn't hurting him....but he wasn't hurting me either, he was slashing me with shadowy claws but I felt absolutely no pain. Then I remember staring him right in the shadowy void that should have been his face and just laughing, laughing harder than I had ever laughed. I woke up laughing so hard tears were streaming down my face. But the thing is I felt much better. Not only about the dream but life in general, my mood had improved a hundred fold. I felt ready to take on the world!

After that the dark figure made a several more appearances, but the terror was gone, I might feel a tinge of fear when he first appeared, but I would quickly get over it and stand my ground and think "you ready for round 2 buddy? I know you can't do a damn thing to me" and he would fade away.

I've had a recurring dream my whole life. I walk down stairs into a solid steel room divided by a wall with a window in it. I walk into the side and there are 2 guys in hazmat gear. Through the window there are giant hooks hanging from a bar that turn into umbilical cords attached to dead babies. Nobody says anything, the hazmat guys just stare at me.

I have this reoccurring dream where I'm walking on this bridge, at the end of this bridge is an island with a lighthouse, surrounded by an endless sea. As I walk toward this lighthouse, the water level rises and eventually spills over the sides of the bridge. I take steps back, and as I do the water level goes down. I want to reach the lighthouse for some reason, but I don't because of the flood. What can this mean?

Just as the title says I am having this dream every morning around the same time for the past 3 days. I walk into the bathroom and sit down to pee (which is strange in itself) and this little pale man walks in who has vampire teeth but he is missing his front teeth. Today I had enough of it and i got up and started peeing on him and he started to try to catch it in his mouth. This dream terrifies me, I think it has a deeper meaning.

This is a dream that has been recurring for years. I’m driving a car, but I cannot control it fully. Usually the breaks don’t work properly, so I drive faster than I want to. Also, interestingly, I’m sitting on the back seat (behind the steering wheel), so my view of the road and traffic is limited.
I never get a big accident, but there’s always a lot of bumping into other cars, scratching lamp posts etcetera 😳.
I wake up from this dream with tight tense muscles.
