If someone reminds you of someone else, it means that he or she is similar to that person in some way, either in appearance, or personality. For example:
You remind me of my brother. You look just like him!
Does he remind you of anyone?
She reminds me of my aunt Mary because her smile is so similar.
We can also use this for places, or other things which make us think of something or someplace similar. For example:
Your apartment reminds me of my first apartment on College Avenue.
That dress reminds me of the one you wore to John's wedding.
This presentation reminds me of the one we saw last year.
It's important to note that you need remind+me/him/her+of to make the complete structure.
