According to Osho, when you pass a night without dreams and feel as if you didn’t sleep, it’s an auspicious sign of deepening meditation: the body rests while an inner witness stays awake, like a small lamp burning within. This gentle, continuous awareness brings rest without dullness; absence of morning fatigue confirms it. As this witnessing stabilizes, dreams fade and recognition of your ever-awake being ripens toward samadhi.
It means your body slept but a tiny light of awareness stayed on inside—so you feel awake, yet you’re rested, which is a good sign.
