Describe your personal religious experiences of God?

If you have had a personal religious or spiritual experience in which you saw, heard, or otherwise felt the presence of God, please describe what it was you felt/heard/saw. What were the circumstances during which you had this experience? What were you doing at the time? How did you know it was God?
Update: I'm looking for details. If you see signs, what kind of signs? If you feel his presence, what does it feel like?
