Soul twin 

Two people who have the greatest bond, and shares the same mind. The two people think the exact same thought even when they aren't physically together. They are basically meant for eachother both physically and mentally!

Man I've definetly found my soul twin, she/he always finishes my sentences or says my thoughts out loud!
