If I'm looking at my bathroom mirror 1 foot away, is my reflection 2 feet away?

Also, if a person were to stand next to the mirror, do they see the same amount of visual details of me or more amount of visual details of me, because they are 1 foot away (just like the mirror)?

I assure you I am not high right now.

Actually, the answer is just yes. In optics, there's the concept of an *image*, which is the apparent point of intersection of the light rays radiated from the point called the *object*. In the case of a plane mirror, the light rays never actually intersect after reflection, but you can trace their path back through the mirror to find their apparent point of intersection. (As a side note, when the rays actually intersect it's called a real image, while cases like this are called virtual images).

Anyway, you can calculate the position of your virtual image, and in the case of a plane mirror it ends up being exactly twice the distance from you that the mirror is. And yes, if someone were to stand right up against the mirror, they would be able to see more detail (as long as they didn't block you of course), because they would be closer to the image.
