on thursday night i went to stay at my friends house and his bedroom door is directly opposite his room mates so if we are going to stay up and chat we have to make sure the door is firmly closed, when it got to around half 2am the door flew open but we both convinced ourselves it was santa. the next day i was in eat getting my lunch and i swear it sounded as if someone gasped or breathed heavily right behind me, returning to the staff room the huge metal door what cannot usually close slammed behind me and spooked everyone! so later that day, i was having an early christmas dinner with my mum and her boyfriend, i was snapping away happily on my iPhone but looking back over the photos i noticed a few were not quite right. please give me your opinions and tell me if im just going crazy or if someone is around and how i could help them?
