Every once in a while, before falling asleep I enter a "mellow" state in which I can conjure mental images dramatically more vividly than normally. I would say that normally it varies between 10-50% of vividness (also depends on the state of mind, the day, whether I'm under the influence of different chemicals), and in this state of mind it's 90%+ vivid.

And I don't confuse this state of mind with lucid dreaming: I had spontaneous lucid dreams a few times. They were not very vivid, just as my normal dreams (I dream in images, and they are maybe around 50% vivid).

So, there is definitely a way to experience variation of vividness of mental imagery, by a single observer.

I have this too, especially when I’m really tired. It’s such a surreal yet refreshing experience. I can hear the most beautiful melodies my ears have ever heard, even though I don’t have a musical bone in my body. And I jump in and out of various vague visual scenes (like staring into deep space) during this.

It always makes me question if I’m dreaming or not - and often, it’s the last thought I remember before I actually drift off to sleep. All of this seems to happen during the span of 60 seconds max (judging from my heartbeats), but this has categorically been debunked when my wife once told me I was actually snoring for a couple of minutes.

The melody thing I assume I have not suddenly become a master composer, rather the part of my mind capable of judging whether the music is any good has become impaired.

I don't consume chemicals but do meditate.

As I drift off to sleep sometimes it's fun to shift the inner eye to observe the mind and watch images float across my "viewport".
