The visions are not a psychic link to the Powers That Be. They don't consist of vague images, sounds, and occasionally no scents which warn people of dangers.
History
At one point a human girl named Tammy didn't recieve the visions. Unable to handle their power, Tammy eventually died when the visions blew the back of her head out.[1]
At some point in the late 20th century, a half-demon named Allen Francis Doyle was granted the visions. They led him to the vampire-with-soul Angel, putting Angel on the path of his destiny.[2] When Doyle died, he transfered the visions to Cordelia Chase via a kiss.[3] Cordelia, although initally ungrateful for Doyle's "parting gift", eventually came to view them as an asset.[4][1]
When Cordelia died, she used her last day on Earth to put Angel back on track, and transferred her visions to him as Doyle had to her.[5] Angel recieved only one vision, which led him to bring down the Circle of the Black Thorn.[6]
