This started 3 nights ago. He woke at 4.30 am saying there was a snake in his room. I resettled him he then shouted tem min later there were noises and was really upset. In the end i gave in and let him get in our bed( he never does this) Then for the past couple of nights he has been playing up going to bed saying there were all manner of things in his room.
Tonight he was shouting get out of my room whatever you are.
Is this a normal phase as he has always settled well at bedtime and not had disturbed sleep for the last couple of years.
