My 9 year old son has been afriad to sleep in his own room/bed since age 2. We live in a gaurd gated comuntiy, we have and use a security system, we have 2 100 lbs labradore retrievers and his room is only 30 feet from our room. We have talked to him so many times about why he is afraid and he is mostlt afraid of someone breaking in to our home. When we do get him to sleep in his room he will either wake up his younger brother and get into his bed with him or make him come to his room. Please help.
You seem to be living in a state of paranoia. Your community has a gate around it, guards (I would assume). You have two large dogs, and a security system....
Now I am not a psychiatrist, nor do I play one on TV...but I would wildly speculate that either your family or neighborhood shows concern over the "outside world" getting in at you, or your property. The child is probably picking up on it. (I am assuming he has asked "why" the fences and guards and security systems exist and was told)
