Bret Michaels' father Wally Sychak says he's spoken to his son, 47, who remains in critical condition after suffering a brain hemorrhage last week.

"The fact that he was talking to me, and giving me information, I thought that was great," Sychak tells Extra.

On the phone, Michaels "sounded a little slow, but fine," says Sychak. "He was talking, not as cheerful as he usually is. But I guess he is under sedation. But he understood what he was saying and knew me. Everything seemed good that way."

Sychak says the former Poison front man also is starting to move his limbs again. "They say he's moving his arms and hands," he says. "The best as they could expect at this time."

A rep for Michaels tells the rocker remains "under intense observation from doctors and staff. He's on a lot of medication, and going through all these tests … they're still trying to figure out why this occurred. Doctors are seeing all the tests, hoping the worst is over."

Meanwhile, the rocker's pals are praying for the best.

What's happened to him is "just hideous," his Celebrity Apprentice costar Sharon Osbourne told Us Monday at the NBC Universal Summer Press Day in Pasadena, Calif. "It's devastating, and it makes you feel all these different feelings. Your heart goes out to his family, your heart goes out to him. He's the nicest guy in the world. And then you start thinking about your own mortality. You start thinking, Oh my God. It just makes you appreciate how lucky we all are."
