Ideas needed on how to tackle this one...

Is there something " special" he could take with him into bed? a teddey who can keep him company and help him be brave to tell the scary thing to go away?
do you have a night light? if not maybe you could turn one on to help him feel safe?.

I hope he feels safer tonight

I'd ride it out. offer security at night and talk about it during the day.
