Between dreams and awake

I dreamt something last night that was wonderful and at some point felt my body at the verge of waking. However, I did not wake entirely and was completely unable to move my body and had not 'let in' the lights, sounds, shapes of the world. (I cannot even confirm if this pseudo awake state was even real or part of a dream)

In any case, whatever it was that I had felt in dream, moved by it, I felt tears. These tears that warm the body and the mind, because they are so unreal, seem grander than they may even be. They equal the greatest yearning, the grandest wave, the surfeit heart of something completely undefined.

I'm crying for what reason? Such emotion for something that was literally a minute or less of REM sleep?

I'd like to imagine our souls and minds having these little vials of pure emotion. They are slowly consumed like a secret elixir. But every so often, i'd like to imagine the vial bursting and emotion just bursting from your every pore, so much so that you even cry---and the tears are of another substance. , maybe even part of that elixir that had burst...
