I have a 5 year old son who's been waking up at night and has been having nightmares for 3 months now, and he's not been able to sleep for more than 2 hours. Just yesterday night I heard him screaming, "A GHOST IS HERE! HELP ME MAMA!" and I am really concerned about him...any tips on this? He is diagnosed with ADHD and dyslexia, and has been notified to being with ADD as well.
