Funnily enough i changed bedrooms in my house and its happened in both, almost identical. I often wonder if i did actually wake up or dream it but theres always a sign that i actually gotup. Normally ive launched the chair away.
I woke up to a big fuck off spider on my body a few years ago, my old man wasnt pleased to be woken at 4 in the morning.
In general im a poor sleeper, normally 2/3 before i can nod off and the slightest noise wakes me.
