Over the past few months I have had several dreams where I have become aware that background speech, incidental to the dream 'topic', has actually been gibberish - e.g. presenter on TV that happens to be on, public speaking, etc. This has alerted me to the fact that I am dreaming - my brain is simply not filling in the detail - and I've usualy woken at this point. The question is: has this always been the case and I've just not noticed this before, or is my brain losing the capability to fill in such detail as it is getting older
