Thank you, as ever, for your replies. I've had better recall over the last few days but nothing lucid as yet - I'm banned from setting an alarm in the night by my wife so I've had to be a bit more creative and drink plenty of water before bed instead, but it's a little unreliable for timings!

I remember dreaming last night when I woke up a couple of times but didn't write anything down as I don't want to disturb my wife too much - I'd have to sit up in bed or get out of bed to go and write on a table. Is there any way round this other than just getting up and getting on with it? I convinced myself in bed that I'd remember my dreams, and then when I woke up in the morning I couldn't remember anything. I had a couple of fleeting moments where recollection started to come back, but then I found that I couldn't remember again.
