Imagine this. Its 2am in the morning. You have been tossing and turning in bed for the past 3 hours, trying hard to fall asleep, but your mind just refuses to shut off. You find yourself increasingly frustrated. You check your watch – its 2.30am. You think to yourself “this is messed up. Tomorrow will be ruined”. You continue to fuss in bed. You shut your eyes and it feels like eternity. You lie motionless in bed, but you know your mind is active – actively trying to fall asleep.
