Judging from Daniel's exposition, yes. And from my own experience (if I interpret it correctly), the dark night stuff will diminish in intensity, but a predisposition to pondering and brooding remains. And I certainly haven't been able to pick up where I left off.
My experience was in childhood, and the psychological and intellectual development during later childhood may have had a kind of healing or scarring effect on the dark night. I really haven't thought about this too much, but your post got me remembering.
Anyway, here it is:
I used to take a word (I'd just learned to write in school) and repeat it endlessly, disassembling it into letters and sounds until it felt strangely meaningless and disconnected, floating by itself, as it were. I found it fun to "destroy" that word in this way, and usually did this at bed time because I wasn't tired yet. So one night, as I was dozing off, looking at the wardrobe door, I had this vivid half-awake experience: God tossed the entire globe of the world at me, from in front of the wardrobe door, yet far away, several times, but I failed to catch it. I myself felt oddly huge, out of proportion, watching myself somehow, from a perspective of great distance. And all this was accompanied by a soundtrack like the first few bars of Jimi Hendrix' "foxy lady" at full blast. I was awake afterwards, and really scared, if I remember correctly.
I quite possibly am misinterpreting this experience, and it's a long way back, about thirty years. Maybe my parents were throwing a party, playing Hendrix (though that wasn't their kind of music). My mother had been telling me classical mythology stuff around this time, so maybe the Atlas myth played into this, I really can't tell for sure. I never had any monsters in my wardrobe either. I've been a brooding, solitary type all my life.
Isn't projection fun?
