Mind over mirror

You'll be a vampire, if ever so.

erm, acktually a mirror is only considered a mirror with the reflection, if it doesn't have the reflection then it wont be a mirror anymore ☝️🤓

how does one know if it has a reflection or not, without looking at it? Is it simultaneously both a mirror and a not-mirror? Does it exist if there is nobody there to see it?...

well if a mirror doesnt have a reflection then it will just be transparent or tinted glass, cuz normal glass also has a reflection
