Tapping into it - Tradução em português

I was watching the serie "Supernatural" and then I came across this dialogue:
Sam: "Andrea said the kid never drew like that till his dad died."
Sam: "There are cases going through a traumatic experience could make certain people more sensitive to premonitions, psychic tendencies."
Dean: "What if Lucas is tapping into it somehow?"
Well, someone knows what's meaning of "tapping into it" in this sentence?
