i had a really long answer typed out which was lost during the AB update.
Its just a dream, dont read too much into it. I had recurring dreams throughout my pregnancy that my sone (due 15th june) would be born 15th may. The date always came up and i panicked that my baby would be prem. I had bags packed for hospital early, always had notes with me and worried with every twinge and pain baby gave me.
15th may came and went, no sign. 15th June came and went too and a very lazy baby finally made his appearance on the 2nd July.
So dont take much notice of your dream, apart from maybe see your mum more if thats what is worrying you
