Mugwort has long been used as a visionary herb. This is because it has some mild hallucinogenic effects (just like wormwood) which can help to amplify psychic visions. If kept near the bed it’s thought to induce prophetic dreams and omens. Mugwort’s psychoactive effects can be absorbed through the skin so you should be cautious if you are gathering it. Its effects are felt most strongly when asleep or in a trance state.
