When it comes to equipment, I don't have anything that could be considered a full kit of survival gear. However, I have a few things I might lug along if leaving the comfort of home, or use if the usual comforts isn't available at home.
Compass, basic first aid kit, knife (https://en.wikipedia.org/wiki/Mora_knife), shell clothing (as insulation generally is better built in layers), A M/90 "Värmejacka" (an army coat) to keep warm while being still in cold weather. Small portable camping kitchen (alcohol burner) and an oil lamp gives for longer blackouts (which I haven't experienced since 2001). Using a tent indoors is a good way to conserve hear, but I don't think I would be able to put up my tent anywhere in my apartment, without having to move around some quite large and heavy furniture.
