Our toddler just woke up, trying to get them back to sleep - suddenly a massive flash of light, less than a millisecond, definitely in the room, not from behind the blind/from outside. Both DH and I saw, nothing seems to have tripped in the room, all sockets working.
I refuse to go back to sleep, DH is being very blasé, and telling me to "get over it," I'm genuinely concerned about a fire risk.
AIBU to not rest until we've worked this out? Any ideas what it was?
