求翻译：我睁开眼睛，发现自己躺在床上，还是在疯人院里的床上，王奶奶他们都为在床边。怎么可能一切都只是一场梦呢，我有点怀疑现在还是在做梦，一直都没醒过。甚至不知道，自己是究竟什么时候睡下的。是什么意思？

I opened my eyes and find myself lying on the bed, still in Bedlam hospital bed, Grandma Wang they were in bed. How could all just a dream, I wonder now and in the dreaming, always have never woke up. Do not even know that he is shuixia what time.
