Its just your brain observing itself and sometimes believing its own BS. According to Nichiren Buddhism the mind is a spectrum of various levels. Practically we can condense the described levels into:

Awareness of the world (sense and thinking)
Consciousness of the self/ego (identity, concepts of good and bad, intellect…)
Subconsciousness : instincts, desires, fears and karmic tendencies …
The deepest field of subconsciousness is the Buddhanature, which is the mind of enlightenment of the individual. Enlightenment is awakening to the Dharma, the cosmic aspect of the universe.

Or you can stay right where you are and pretend you are the center of the universe. Its all good unless you believe you are the king by divine right or the rule master that must be obeyed like the narcisist.
