Definitely. 20 years ago when homes were not littered with LEDs all over, I would wake in the night to total blackness. I could still find my way around the house just able to see based on what is I suppose a noise floor of ambient temperature. Go into the kitchen & behold the stove top emitting 'bright' white light, from I suppose a temperature of around 30degC /90F.

Obviously everything is a blackbody, but those photons surely can't be 'single' visible ones.

Gosh. I used to have pretty good night vision and recognise what you mean about "see based on the noise floor" - but I never had an experience like seeing the stovetop heat. Remarkable. I wonder how much variation there is between people? Unfortunately mine's faded with age so I don't think it's worth my trying to see if I can see that myself now...

Did you consider you were seeing (very low amounts of) visible light? Temperature had nothing to do with it.

Is it possible that your house was illuminated by ultrashort infrared laser pulses?
