What does it mean when you dream about an obstacle?
Dreaming about encountering an obstacle can reflect feelings of being blocked in our waking life. Can also involve the ways we block ourselves, or, alternatively, indicate uncertainty and inhibitions.
In air operations, a natural or artificial object which by its geographical location requires that its vertical dimension be considered in establishing the permissible flight paths in an area; this leads to the concept of the fictitious height for various obstacles; for example, a moving vehicle 17 feet high is assumed to be on an interstate highway 15 feet high, and thus the area is assumed to have an obstacle 32 feet high.
