If you dream of passing through a tunnel, it tends to carry an unsettling energy for matters of business and the heart alike. Should you find a train barreling toward you inside the tunnel, take it as a warning of potential health troubles and an unwanted shift in your professional path. Riding through a tunnel in a vehicle points to frustrating business outcomes and travel that drains more than it rewards. A tunnel collapsing around you signals the threat of failure and adversaries who wish you harm. Simply peering into the mouth of a tunnel suggests that a difficult, high-stakes situation may soon demand your full attention.
