The following is a technique/game I would play in the car when i got bored...but actually last night I thought of how this would help when you go straight into a dream after falling asleep.....

What I do is I close my eyes (if you are not the driver and if you know which way - at least WHERE- the driver is going - preferably a short enough distance) and you must pay attention to your 'photoghraphic memory' and your memory in general of how long/short streets are - and you must imagine it and pay attention otherwise you'll get lost...Try it and if you still don't understand send me a PM...

This can be applied in the sense that you are having your eyes closed while not falling asleep or daydreaming, you must be present - in a sense - or you 'lose' the game...

I think this might help focus, maybe you need it maybe you don't, I just wanted to put this technique out somewhere....i hope this helps
