To Sleep, Perchance To Heal?

I don't get it, and right now I'm not going to try, but later on I definitely will give in and do some picking around Google.

Here's the thing: Last night I went to bed feeling that I just could not take another step up the unending life hill. This morning I woke with an amazing blanket-like sense of peace.

Nothing's changed. In fact, the cards are stacked against this sort of feeling.

1. I woke in the middle of the night and couldn't get back to sleep for about a half hour

2. I had a really disturbing dream that I won't detail here, but suffice it to say it involved my family and moving away from my therapist...my anchor source for the past seven or more years

3. According to my doctor, the level of Adderall and Effexor are at their lowest in the morning. Which means I should, and should expect to be profoundly depressed.

And yet....I feel as though I am wrapped in layers and layers of calm; my brain feels like it is swaddled in protective paddings of warmth. What is going on?

I feel the pull of Google and search terms but I'm going to resist and go and work out. I have a gut feeling that trying to decipher this state of mind will wreck it, whereas just going with the flow will prolong the state. So...more endorphins it is.
