Explosion
An explosion is what was pressed down blowing out at once. Tradition read the great sound and flame as force, so an explosion you walked away from unhurt was taken as a blockage opening. Watching from a distance means someone else's affairs are erupting, and preventing an explosion signals attending to what you deferred in time. It comes up often when a lot of feeling has been held in, so reading it as a call to see what is being suppressed is fair enough.
An explosion is the scene of everything held in coming out at once. How long it had been pressed down only shows once it has blown. Whether you stood at the blast or watched it from a distance is what divides the reading.
Readings by Situation
An explosion you walk away from unhurt
A good omen that something blocked opens. Tradition read a great sound as force on the rise. If something has been pressed down a long time, read it as the moment it releases.
Watching an explosion from a distance
A sign that someone else’s affairs are erupting. Read it as change around you catching your eye. If you were only startled, it is not aimed at you.
Preventing an explosion in time
A good omen of attending to what you deferred. Tradition too read averting harm favourably. Checking whether something has gone untended will settle your mind.
Watching flames spread
A sign that what blew out keeps spreading. Tradition sometimes read fire as wealth, but if it grew past what you could handle, read it as a call to cut back what you have underway.
An explosion dream does not forecast a real accident. It is closer to a signal to notice what you have kept down. Writing out what you are holding in cuts it down to size.
