Anyone have experience with sleeping tablets (stilnoct)?

I’ve used them before so know what to expect, i.e. stay in bed and keep away from the phone, etc.
Low and behold, I wake up to find I sent less than a handful of nonsensical text messages. I’m prone to making sense for the most part (at least I’d like to think so) so I’d imagine it was confusing for the person I was conversing with.
I’ll have to explain my “out of character” behaviour today.
Has anyone had any weird experiences on this kind of medication? Humourous or otherwise?
