Why does eating strong cheese immediately before you go to sleep cause very vivid dreams? I thought it was?

just an old wives tale until I tried it last night, I had 3 slices of toast with generous helpings of mature English cheddar on all three of them. During the night I must have had 9 different extremely vivid dreams, I can remember every one of them in detail and each one was completely different from the next. On a normal night I don't remember the dreams very often so I was surprised that it works. If you don't believe me try it yourself. (just make sure you brush your teeth well afterwards )
