Had a dream that was sci-fi/fantasy, probably because I've been helping plan D&D stuff of the same genre with my brother.

The dream started with me coming across an alien artifact that once it came into contact with me awoke some ancient blood in me.
I suddenly gained the knowledge and power of some kind of ancient space dragon that came to Earth in the distant past.
Among the things I gained was the ability to transform into a true dragon form as well the information of how to make use of it.
My first goal was to enlighten mankind and get us working together on improving our technology with my new found understandings
not only for the sake of making us better but also to prepare us for what else was out there in the depths of space.
I became some sort of figure with immense power both literally and in terms of politics as I was the source of this new knowledge.
I quickly took on the role of both ambassador for when we did encounter alien life as well simply the guy who could get shit done.
There was a big commotion as it was brought to me attention there was a spy/assassin in our midst from either a terrestrial group
or an alien one, they turned out to be some kind of highly sophisticated android or otherwise synthetic being that looked like a human woman.
They had this sword that was either high tech or magic in nature along with some kind of stealth field like ability they used to get around.
My new found powers helped pick them out during an attack and I basically used some magic command word on them to make them freeze.
I then chocked slammed them and took the sword away with the other hand, then immediately took them inside while unconscious.
Once inside I went to an elevator room kind of spot and demanded the A.I operator to take me to "maximum security" to which they
seemed confused at first but then saw what/who I was holding, after saying "now!" they got us there just as the spy was coming-to.
I through them into a cell and kept the sword to lock up elsewhere with plans to question the spy later, there was a montage afterwards.
The spy was fairly average in height and frame for a young lady in her early 20's with her most striking feature being her hair which
was sort of peacock like in colours and was tied in a top bun like style that made her head look a bit like a tropical fruit or something.
The montage included snappy exchanges of words and the occasional failed escape attempt, there was another A.I that acted like
a messenger or patrol that would holo phase into the cell, unsettling her every time as it was kind of basic and doll faced.
The montage came to an end with her having started trying to dig her way to freedom having somehow disabled an alarm against such acts.
As she was drilling I was coming down to bring something to her attention, the doors to the cell opened and I just stood there while she froze.
Jump cut to the two of us in an elevator on our way to the roof as she attempts to make an excuse, I just stand there calmly and tell her
that there's something we want her opinion and or help on regarding an alien visit, as she starts objecting I hold out her sword as if to offer it.
She's confused to say the least but when the elevator reaches the rooftop she starts realizing what's going on as she looks straight up.
The view pans like a camera to show the sky above the city being taken up by mostly one thing, a giant creature of unknown origin.
She reluctantly helps by telling me what it even is and why it might have shown up here, it was somehow related to the whole dragon thing.
It also seemed like she didn't quite know who or what I was (failure in her mission briefing?) as she seemed surprised when I turned full dragon.
I sort of man-handled her while in dragon form and picked her up by the scruff to set her down further away while I confronted the issue.
She just stood there in silent contemplation as I attempted to signal and commune with the creature, an exchange of some draconic speech
later and it was clear the creature meant no harm, though some of its scales were falling off onto the city bellow which was a tricky thing to fix.
The event concluded with the spy agreeing to work with us, apparently her former employers weren't what you'd call fair or caring.
Another jump cut later and we see the spy going about daily life on Earth, evidently she has some sort of bond with her sword and can
communicate or even argue with it, it was mocking or maybe teasing her for having adjusted so well despite early complaints.

That's about all I remember about it, there were other mixed dreams but nothing coherent enough to write about.
