Sleep and dreaming: Where do our minds go at night? | New Scientist Jan 2013
"dreams tend to be silent movies – with just half containing traces of sounds. It is even more unusual to enjoy a meal or feel damp grass beneath your feet – taste, smell and touch appearing only very rarely. Similar studies have tried to pin down some of the factors that might influence what we dream about, though they have struggled to find anything reliable."

"the idea that sleep helps to cement our memories for future recall "

[Mark Blagrove at Swansea University]'s "team has found that memories enter our dreams in two separate stages. They first float into our consciousness on the night after the event itself, which might reflect the initial recording of the memory, and then they reappear between five and seven days later, which may be a sign of consolidation"

"the sleeping brain also forges links to other parts of your mental autobiography, allowing you to see associations between different events"

"Perhaps the intense images are an indication of what a difficult process it is integrating a traumatic event with the rest of our autobiography."

"Despite these advances, many, many mysteries remain. Top of the list is the question of the purpose of our dreams: are they essential for preservation of our memories, for instance – or could we manage to store our life’s events without them? “There’s no consensus,” says [Patrick McNamara at Northcentral University]."

"some research suggesting that TV may have caused a major shift in the form and content of our dreams"
