The realities are... it is difficult to explain. The world you are from is not the same as this one, despite both containing the same places. There are many people here you may recognize as being from fiction - television, films, books, comics, and the like. In their worlds, they are not fiction.
I do not know if a tazer would do more than slow them down, I'm afraid.
If you tell me where you are, or a close estimate of your location based on your surroundings, I will come and get you.
