Hi all, this is my first time to the NAS community. I have a child who has high-functioning autism. My child told me today that they hear beeps in their head when there is silence - repetitive pattern of noise that disappears when talking or being talked to. They know these are not real sounds, and only in their head, and they weren't too alarmed as it's apparentely been that way for a long time. I'm not sure what to make of this - I'm guessing it's some form of stimming. Has anyone else had an experience like this? I'd really appreciate hearing from anyone who has. Many thanks!
