Dr. Ozbay says spirituality is often used as a coping mechanism for people who have experienced traumatic events such at 9/11. "Some of my patients talked about having experienced a feeling of a presence in a religious context and that it wasn't clear to them what kind of presence this was. These are fairly common, but the communication with the other world is not something that I've heard. There's something very threatening about randomness and how random everything may be which implies a rather dangerous, chaotic world. Belief in a system, in a god, or angels may be more comforting as an explanation."
