Hi Kerstin. I

If death or illness isn't an issue to you in your waking life right now, death in a dream often refers to a change in your life - the end of something old and the start of something new.

You were getting conflicting advice in your dream - the nurse telling you to keep moving and the people in your house who want things to stay as they are (you should still be dead).

That sounds like you are conflicted about something that may change or is changing in your life. Part of you knows that things have to change and part of you wants them to remain as they are.

The nurse is the part of you that know's what's best for you and what's good for you. She'll make sure you'll take your "medicine", even if you don't want to.

The people in the house who are angry at you for not being dead can represent your own anger at having to deal with the change.

Since you couldn't see who the friend was, it's likely that this friend was a part of yourself - the part that is able to look at things calmly and rationally and try to make sense of it all.
