Do you ever wake up and know that you have dreamed something completely wild but not been able to remember it? Last night you know that you had a whole novel going on in your head, but now it is a blank piece of paper. Why do we forget so easily?
Most of our dreams occur during REM sleep , or Rapid Eye Movement. It is characterised by just that, a pattern of shifting eye movements under our eye-lids while we are asleep. It is during this time that some of our most bizarre dreams can happen, many of which JK Rowling would be proud of.
However mundane our ordinary life is, it is while we are asleep that we can do crazy and impossible things, things that seem perfectly reasonable when we dream. The sequence of time and events can be mixed up, the logical becomes confused with the illogical or impossible. It is when we dream that that our wildest dreams or worst nightmares can become real.
Often the subject of our dreams is worlds apart from our real life, while at other times it is spookily similar.
It is just such a shame that so often we only have a flickering memory of it when we wake up. Whole worlds are lost to us because of our inability to remember.
