NBA players are known for their intensity, strength and peculiar superstitions. But did you know that some ballers believe in ghosts? In fact, one of the biggest stars in "The Association," San Antonio Spurs Forward/Center Tim Duncan, is convinced that supernatural presence exists. These ghosts apparently reside in hotels various teams utilize during their myriad road trips.

Duncan and his teammate, fellow big man Jeff Ayres, recounted one haunting experience to Dan McCarney of the San Antonio Express News. While staying at the historic Claremont Hotel in the San Francisco Bay Area this past weekend, crying ghost babies apparently invaded their rooms!

Maybe Stephen Curry and his Golden State Warriors, who the Spurs were in town to play, wanted to gain a competitive edge and pull some elaborate prank on their competition?

Here's what the six-foot-nine, 250-pound Ayres had to say about his stay:

"You get in at whatever time. I took my room key. I could hear stuff in the hallway, like people in their rooms. So I'm thinking people are watching TV or whatever. So I get to my door, and my key doesn't work, but it sounds like there's somebody in my room. Like I hear a little baby, not crying but making noise. I'm like, 'What the heck?' I keep trying my key and it doesn't work. So I go downstairs to get a new key, and I tell them (somebody's in the room).

He want on to say that the security guards were called and they found nothing at all:

"So they call the room, and nobody answers. They're like, 'We can get you a new key and send you up with security and make sure nobody's there, because there shouldn't be anybody in there.' Then they're like, 'We'll just get you a new room.' It was the creepiest thing. I heard a couple of other guys heard babies in the hallway, kids running down the hallway. Creepy. I really heard voices and a baby in the room, and there wasn't anybody in there. It was crazy."

Duncan added that he "... heard a baby in his room. There was somebody or something in his room, yeah. I definitely heard something. It wasn't creepy, because I assumed it was really somebody in the room, and they gave him the wrong room. But when they told me the story the next day about calling up there and no one in the room, it's at that point you get chills. I totally agreed with him. There was a baby there, absolutely. I heard about the history of the place, and I'd rather not (stay there again)."

Berkeley, Calif. should be proud. Now the city is not only known for their great university, but for ill-mannered ghosts as well.
