Had been quite sick due to asthma, being unadjusted to lack of air at my families holiday house in the mountains, and a bad cold. Woke up coughing a lot, then blacked out, woke up again coughed, blacked out again, etc. When I finally managed to get up I noticed that my blanket was solid near the corner. Turns out I had been in bed for most of the day and had been coughing up a lot of phlegm.
Much less gross: My mum poring cold tea on my face which had been next to my bed for 2 weeks. Not a fun time, and I still have a stain on my pillow case form it.
