Daughter Of The Mind (1969)

Starring Don Murray, Ray Milland, Gene Tierney, Barbara Dana, Edward Asner
Directed by Walter Grauman
(actor & director credits courtesy IMDB.com)

A famous scientist is plagued by visions of his deceased daughter, and turns to a parapsychologist for help, who discovers that what he's experiencing is not all in his mind.

A terrific thriller made for television, this film is well-written and directed, and features a convincing performance by Milland as the scientist who turns from logic and reason to faith to accept what is happening to him. He's supported by a great cast, featuring Hollywood veterans like Tierney, Virginia Christine, Don Murray, and John Carradine (in a small but pivotal role), as well as Ed Asner, (before the Mary Tyler Moore show), excellent as a dogged intelligence agent trying to prove the visions are fake.
