Feeling a touch while asleep is read as a sense of unseen presence or influence. Dream books take it as heightened sensitivity, and as something asking for your attention.
When this appeared in your dream, what were you feeling?
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.
