If you want really vivid dreams set your alarm to go off every half hour from about 5am (presuming you go to bed about 12am and wake up at say 8am)

I did this and had the most spectacular vivid dreams. Some of them were lucid as well. The memory download is amazing. A good tip would be to speak into a recorder (most mobile phones have them these days) rather than writing the dream as writing it can take some time. But even without recording, you will remember a great deal.

I've become a member of the mindset that dreams are just as mind blowing, if not better than O.B.E's.

The only thing I found with this technique is that I was extremely tired the next day.
