I feel like a cat in one of those cruel sixties experiments you learn about in Psychology. You know, the cat that was placed on a tiny platform in the middle of a swimming pool and every time it went into a deep sleep its muscles relaxed and it fell into the pool.
For the past two nights, it feels as if every time I have entered that sleep phase, I have been awoken by a little voice shouting "I've been sick!" or "I'm going to be sick!", and last night, "I feel awful", "I've had a terrible, sob, nightmare" and then at 2.30 a.m. "Mummy, can you rub my brow?".
The cat was completely crazy by the end of the experiment.
