Last night I had a dream I think I dreamt that I pulled and slice of multi-grain bread out of the cupboard. I looked at it and put it back.

I told my mum about it and she said there was a single slice in the cupboard in exactly the same place as in the dream about a week ago. I may have pulled it out, I dont know.

Does anyone know if there is a way to test if something was a dream or not?
