A numb hand or face is traditionally read as feelings you have stopped letting yourself notice. Dream books link it to a stretch of life where shutting down felt safer than feeling everything.
Where in your waking life have you met something like this lately?
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.
