I thought vivid dreaming was an indicator of sleep interruption, not quality sleep. IIRC dreaming happens during our deepest sleep when you would not normally be easily woken up. Remembering your dreams mean you woke during that time.

I thought that too, but what seems to happen is that I wake up remembering a very long dream rather than just a jumble of dream snippets from the night.
