Sort of cigar - but it was fat - more big in the middle. At first I told myself it was a kite or black garbage bag, but it's impossible

I was driving and saw this sort of cigar shaped black ufo. It was darkest in the center, where it kind of looked pushed in. A triangular "fin" sticking out, but no sharp edges. Then it literally "pulled apart"... almost like thick cheese or oily - kind of slick looking. I was keeping my eye on it, waiting to see it past the tree, but it was gone. Around 2 -3 hours later, I went back to the location and could not see it at all. Part of me was thinking - was it like some kind of large birthday party balloon? (I really want it to be that - I don't know why. I want it to be a garbage bag, kite, or birthday party balloon). But it was gone. So the color was between black (in the middle of the "cigar") and gray. It didn't change from those colors, but the shape changed. Strangely, when I was filling out this report, I discovered I felt / had time / memory loss. I completely... I had a very hard time explaining to myself what I was even doing in that area. I was in a remote part of a canyon prior. I had never gotten that lost before - and strangely felt "ok" with it. Normally I am not ok not knowing where I am. My phone was also completely out of battery / power. Prior ... maybe 20 or 10 minutes before seeing the craft, the gps went nuts. I also remember now hitting a garbage can. I have seen Aiten also have extreme issues with gps in that same area - but the craft was seen later miles away. There's a sort of "hazy" or "dreamy" feeling starting the time I went into the canyon. Uhhhh... like I wasn't quite myself. Like I was ok with things I'd normally not be ok with.
