How to meditate before going to bed and after waking up? I read on some online page that the time before going to bed and immediately after waking up is benificial to meditation. I searched over internet but there aren't any specific instructions about any such Buddhist practise. 

Is this true? Is there any special meditation we can do in this time?
Actually there is a reference to this and it is this video where the Dalai Lama advises a group of people to meditate before going to bed and immediately after waking up.

Before after waking up: our mind is filled freshness,you are relaxed and generally this continues to the rest of the day! You can face your obstacles easier!

Before going to bed: The stress built up during the day has to be gradually released before you can fall asleep.You too help your body relax better!
