"My bed tipped last night!" That is what I would say to my parents when I was very small when I was sick. I still sort of remember what it felt like. It seemed that one of the legs on the bed frame was shorter or broken and that the bed was constantly shaking or tipping. I'm not quite sure what made me feel that way. Was I just dizzy? Feverish? Have some sort of inner ear problem? I know it wasn't the bed because one time the "tipping" was really bothering me and I got up to tell my parents. On the way to their room I felt the whole house tipping and I fell down in the hallway.
