Damn, the exact same for me.
Except recently I've been trying to form them even outside of fevers. I often get restless if I can't find the "correct" loop. But when I find the correct one, it's very nice and I can kinda just focus on it. Often it's humanoid shapes bending and stretching in a bouncy fashion, accelerating exponentially. They have to really gain a shitload of momentum: imagine a person shape stretching towards a fish-eye lense - deaccelerating to a stop, then quickly accelerating the fall towards the extremely far-away-seeming distance. Dunno how much people here know about animation, but imagine the distance travelled starting at the far out stretch (close to "camera") shown as so:
Some nights I feel more at ease watching clown-like humanoids bouncing up and down a bit in a star-shape with their limbs (arms and legs spread) while flickering and being distorted like static waves extremely rapidly.
Sometimes it's not shapes though, I remember the first times I experienced this during fevers that I envisioned riding a rollercoaster, again really focusing on the acceleration. And there was a really heavy slow paced flow to it.
Other times it's best with shapeless stuff folding in on itself, again accelerating and deaccelerating. I wonder what my liking for heavy beat-like acceleration has to do with.
