Any chance you blacked out but didn't realize you did? A couple things you wrote made me think that could be plausible. It's happened to me a few times that I am aware of and probably some I wasn't. 60mg is def capable of a black out and if you were already feeling it while still tugging that remind me of a particular journey that hit me so hard my body just expelled the vape like on auto pilot and thank god it did because ti was a doozy.
