Adivse please.

My 10 year old is having a waking up at night scared out of his mind probably. He has always been a bit scared at night. Scared of robbers breaking in. He sees things moving and thinks he hears things moving. Or a light moving. We have tried many things like a night light, that was to bright and he would come wake us up to tell us he could not sleep because the light was to bright. Bye-Bye night light. The office is right across from him and he would see light from the computer or maybe an alien space ship, come to us wake us up and tell us. So we closed the office door. Now he thinks he sees the office door opening. The other night it was so bad he was shaking all over terrified. So due to being so tired he sleep with us briefly until I sent him back. We encourage him to pray to trust that God is in control and that the house is safe but if something were to happen it would happen and God has a greater plan than we can understand. Last night 3 times he came in and woke us up it is getting worst not better. He feels we are mad at him and we let him know that we are not mad just frustrated with the situation. We told him not to get up to go back to sleep that is not working. I know he is truly scared and not trying to just sleep with us we never let him, but I feel punishing him is not quite the right avenue yet . What should I do. Any suggestions would be much appreciated.
