A panic attack can cause a you to think something awful is going to happen, that you can't escape, or that you might lose control. Some people who have panic attacks say that when the attacks are happening, they feel like they can't think straight or that they're "going crazy."

Such panic attacks only last a short time. But to a person who is having one, they can feel much longer.

So what can bring on such a panic attack. Flying, heights, spiders, the dark. Any or all of these can cause a phobia in people including celebrities.

A national survey of 4,000 adults and 1,600 kids revealed that 56 percent of adults admit they now have a fear or a phobia. The survey found that 86 percent of adults and 91 percent of youngsters admitted to being afraid of something.

Nearly one in five adults also said they are scared of more now than they were as a child.
