No. It is normal to have a nightmare every now and then. Frequent nightmares might suggest that you are dealing with very stressful situations. It might also result from some extreme situations you have faced in the past. It is true that nightmares are more common in people with other psychological problems. Examples include depression and anxiety. But this does not mean that you are crazy if you have frequent nightmares. By Donald R. Townsend, PhD Updated September 12, 2005
