Dream

I recently had a dream that bricks were being placed in Masjid un Nabwi and there was a competition between who would place the last brick. The competition was between me and someone else and to win we had to recite a Surah from the Quran. I don't remember which it was but I know it was one I have learnt by heart. However when it came to reciting it I was unable to. (I learnt the last para of the Qur'an however I have forgotten many of the Surahs from there but in the dream it seemed like a small Surah that I should've known).
