There's no such thing as a "Jedi mind meld"
Actually, there kinda is
Force Meld, otherwise known as Jedi meld or Battle meld, was a technique where a number of Force users joined their minds together through the Force, drawing strength from each other. A refinement of battle meditation, it was known to the ancient Jedi, though dangerous. While battle meditation could influence both the Force-sensitives and the insensitives of both sides, Force Meld concentrates on coordinating and improving the Force-sensitives of the user's side.
