Counselor Troi's empathetic powers play a lot into the plot twists of ST: TNG. But such things are unlikely in real life.
The reason Psi phenomena like telepathy, telekinesis, ESP and so forth figured prominently in TNG is because is was featured in the original series. Back then they were studying Psi in laboratories, and they thought there was something to it. There isn't. Studies on things like ESP have proven inconclusive. And things like spirits have never been demonstrated in a lab.
