No. They are not real.
Some vampires can.
They have no mirror image.
I believe vampires having no mirror image has something to do with the fact that they have no soul. In a metaphorical sense, a mirror is supposed to show you exactly as you are and in this case vampires can be considered to be "empty", since they have given up on their previous life and existence.
Vampires don't need to shave.
Yes. But they do not appear in mirrors.
People used to believe that your reflection was really your soul. If you broke a mirror, you broke your soul as well. Note from PickledOnionGirl: That's why Vampires are believed to be invisible in a mirror. Vampires supposedly don't have souls.
Yes everything has a reflection
There are no such thing as vampires, so telling the difference is easy. If they exist, then they are not a vampire. If they exist, then they are human. Vampires are fictional, like elves, fairies, Santa Claus and trickle-down economics. [Alternate: Hold a mirror up in front of them. If you see their reflection in the mirror - and you will - they are not vampires.]
Actually you can. This is one of the more incredulous claims for vampires that is difficult to conform to known physics. Some vampires are not comfortable with what they have become and shrink from seeing themselves in a mirror. Denial.
Because the need souls to see them selves in the mirror.
In vampire folklore, it is said that the undead do not cast a reflection, so if there was a mirror nearby their identity could easily be detected.
According to the currently popular drift in teen-age literature, vampires are not seenin a mirror.This in effect guarantees us that without exception, everything that's visible directlyis also visible in a mirror, since vampires don't exist.
