To put anger and rage into a bottle and then close it mught one day lead to an outburst. It looks for an outlet somewhere 8else) and you lose control over it.
Anyway, just now you want to control your rage ... - but is "bottling" the right way ? What do you do with all this pressure ? What will it (the pressure) do ? Especially when the bottle isn't safe enough anymore ?
It might come to an outburst, yes. That's what the boy in you did in the dream. He did - maybe - what you would like to do but never did - or never had the chance to do.
Maybe you could try directing it somewhere else, and not "bottling" it anymore until it outbursts uncontrolled ? Maybe you could lead this "energy" into something ? art, for example ?
Maybe that's what your dream wants to say to you ?
