Anesthesia is traditionally read as a wish to be spared from feeling something for a while. Dream books link going under to handing control to others and trusting them to carry you through.
Has this come up in your dreams before? What was going on in your life then?
My Cosmic Code has a private dream journal. Write a dream down and the app picks out the symbols in it, shows what dream books say about them and, over time, which words recur across your entries. The journal is stored on your device only.
