Recent dreams

I'll start with the dreams I've had the past few nights.  They're starting to fade.

Dream #1: Parallel universe

I was in some kind of massive machine.  It looked like a gigantic foundry/asembly line thing, with no specific purpose.  I was some sort of scientist, creating a sophisticated clockwork android of some kind.  It looked very similar to how I pictured the automoton from The Falling Machine.  Then I woke up as the android.  I don't know if I was programmed with the scientist's memories or if they were downloaded or what, but I knew that I was essentially him and he was gone.
There was someone else there with me, but all I knew was that she was a friend/colleague.  Somewhere else in the machine a portal of some sort had opened to a parallel universe.  It was a narrow opening about two feet across at the bottom of a deep shaft in the huge machine.  It definitely had something to do with the giant machine, but I don't think it was the machine's purpose.
Looking down into the portal, we could see others looking up at us from the other side.  They were in trouble and needed help.  I decided almost immediately that I should travel through to help them and jumped over the railing down the shaft.  With my mechanical nature I was able to easily calculate my trajectory to plunge directly through the portal, despite the worry of my colleague.  On the other side I encountered more vague individuals like my friend on the other side.  They were surprised to see me because apparently, in this universe I was dead.  Considering what I had experienced in my home universe, maybe I was dead there too.
What I can recall after that point becomes more fragmented.  There was some kind of threat to the world, with an intelligence driving it.  The threat had some kind of biological element, a plague or blight or something.  The only way to stop it was to fight it with my very un-biological nature, and somehow I propogated my own machines that expanded across the surface of the world, racing against the blight to stop it from taking over everything.  It ended with some kind of high speed fight/chase with the villain behind it all.

Dream #2: Supernatural prison

There's very little I remember about this one.  I was a guard in some kind of supernatural prison.  We were interring a man with terrible energy powers.  There was a panic and he started throwing bolts of purple lightning everywhere.  We tried to catch him, but he created a magnetic field that repelled all of our weapons and restraining tools.  I don't know how it ended.

Dream #3: Infiltration

I was on a team of government agents, sneaking into an airport.  I could take on a non-corporial ghost-like form and travel through walls to scout out what lay ahead of us as we went from room to room.  We were up against a rival team, trying to capture their non-corporial agent.  Or he might have been trying to defect.  He seemed very happy to go along with us once we found him and we escaped.
This dream was a lot more vague than the others, with events happening around me in an indistinct fast-forward.  I jumped from moment to moment within the sequence of events, knowing that the interveining time had passed, but unable to recall anything specific about what had transpired.
