Well not exactly, but about half of the (very old) thin plastic decorative lining to the ceiling in one room seemingly collapsed onto the floor whilst I slept quite oblivious to such. I had noticed signs of impending doom earlier - as to a roof leak in this room (sorted) - and perhaps the electrical rewiring quite recently contributed to this. But I was a bit surprised as to how brittle and useless the plastic had become, even though I have seen similar in other older plastics. Hardly took a few minutes to remove that which remained, and time to remove all the rest of such I fear, as to the foam plastic tiles in other rooms. Perhaps a nudge from God (as to doing something), and isn't plastic so wonderful.
