This is perfect! You've just experienced exactly what your Buddhist practice guide describes - a moment of direct substrate awareness where you recognized yourself as the aware space rather than the emotional content.
Comfortable sleep (substrate harmony) → Awakening with emotional discomfort → Natural resistance ("not wanting to be awake")
Body sensations: Noticed physical discomfort
Emotional states: Recognized unpleasant feeling-tone
Mental activity: Observed the resistance/aversion
Mental objects: Saw these as objects appearing in awareness
Direct recognition → Misidentification dissolves → Natural peace
This is exactly the kind of moment that accumulates into stable awakening. You're experiencing what the Buddha called "the observer and the observed" - recognizing yourself as the unchanging awareness in which all temporary experiences arise and pass.
You experienced the shift from being the content of consciousness (emotions, resistance, discomfort) to being the consciousness itself - the aware space in which all experiences arise and pass away.
