Nothing on the soundtrack other than my fridge humming and me snoring.
Something might have appeared on one of the overnight films. Might be a head seen from behind, sitting in a chair, but it doesn't look like what I've seen (then again, a digital camera doesn't necessarily see what the eye sees) or it could be a shadow. It's not pixellation, it had become light by then.
I am not confident it's anything useful but I'll try to clip out the bit and put it here for opinions. The whole film is from 4 am to 9 am and there's about 10 seconds of interest so you really don't want me posting the whole thing.
