Ds got really freaked about a Halloween costume a few weeks ago and was scared that a vampire was going to kidnap him (no idea where he got the kidnapping thing from). He now won't go upstairs on his own, frequently yells me when I'm in another room because he's scared - can't/won't say what of, keeps waking up in the night scared of things coming out of his cupboard and is generally nervous.
Any ideas to try to help him get over this? Or have any techniques for him calming himself down. He's 5.
