Let me remind you what self-observation is, because without self-observation no sealing can take place. You are composed of many 'I's amongst which sits Observing 'I'. These 'I's are all looking at a play on the stage: the play represents life. This is the situation of yourself asleep.

When you begin to observe yourself, Observing 'I' turns round from the stage and looks at the audience and notices how each one is reacting. Some of these 'I's are perhaps jumping up and down and shaking their fists at the play, others are absorbed in it, others snoring, and so on. Observing 'I' begins to notice all these different reactions in the audience. This is self-observation.
