magic mirror

Is there a spell were i can make my mirror show people's true nature im dying to know it and use it on my parents,

All right we've had a couple of these things crop up now. I know that your profile says you've been into witchcraft for a few years but if that's true I'm afraid it's sounding like it's been focussed in the wrong place and I strongly recommend you take a look at the plethora of information on the so called basics here on the site. Magic is a metaphysical force, not a physical one and from a number of your posts I'm getting the impression that you're barking up the wrong tree.

There may be a way to use an object such as a mirror in a manner of scrying for you to gain an idea of peoples intentions or feelings towards you but that mirror would never show those images to anyone else. Mirrors reflect light not emotion and any adjusted image would be in your head not that of the onlooker.

What im trying to say is i only do water so this is new and its from a legend i know so u wanna know if it will work

Yes, it could show you ones true nature however; you would view it in symbols that you have to figure out the meaning of. It would fall under scrying although it could be another form of divination.
