Dreams as Health Signals: What Sleep Experts Say Your Night Visions Mean

Sleep doctors say dreams are a normal part of REM sleep, likely tied to memory processing and emotional processing. While dream interpretation isn’t exact science, common themes (teeth falling out, being chased, falling, naked in public, failing a test, flying, infidelity, drowning, seeing deceased loved ones, and sex) often reflect daytime stress, fears, and personal concerns. REM sleep concentrates in the second half of the night and helps sort memories, so these nightly narratives can offer insight into your mental state, though they do not diagnose health issues by themselves.
