Thanks shattered and berthegel
I have found out I sleep better with socks on. And yesterday I went back to turn off the temperature totally in the living room as I did before and pulled the curtains again. The cold doesnt reach me that much when I pulled the curtains and I can get enough air so that it felt comfortable, Now its soon summer so it may have felt comfortable right now as its not so cold at nights.
I still didnt sleep the best, as expected, as I didnt sleep good before either, but I slept maybe a bit better
