I had the most awful nightmare yesterday. Do you think they are just filing things away or have some deeper meaning to do with state of mind, or anything else? It involved my DD aged 3.8 and when i went to check on her, she was in the process of waking up, sitting up, and looked at me, smiled and said 'mummy! I was waiting for you' and i said 'why were you waiting for me baby girl' and she said 'because i wanted to cuddle you', put her arms around my neck (just like in my dream) and went to seep smiling. She usually is sound asleep when I check on her, and if she does wake up she is grumpy as anything.
