I don't think we are trapped in boxes. Boxes are relatively easy to break out of, as can be seen with the "jack in the box" analogy. What I see is a transparent glass inner tube that is tinted on the outside. We can see out of the inner tube, but no one can see in. Therefore, people are even more confounded by our emotional outbursts because they assue that since they can't see in the inner tube, we can't see either. This explains why people can't even see the source or reason for my outbursts.
Also, any effort to break out of the inner tube would be futile. If I were to push against the inside of an inner tube, it would only make me slide around inside rather than breaking out like a jack in the box. The inner tube also represents the constant cycles of emotion. Rather than starting and ending, my emotions keep going around in circles because they keep getting fueled, and I can't seem to find a solution to end these cycles. Once these cycles are spinning around faster and faster in an attempt to get out, they eventually make the tube explode, making for a more violent outbreak than a jack in the box.
Additionally, the function of a jack in the box is apparent. Crank it, and you will hear music until the jack pops out of the box. Then you put it back inside and crank again. With this heavy glass inner tube, the function is not nearly as apparent. It's too fragile to play with, you can't float on it in water. It's just there. Likewise, we often don't know what to do with our emotions most of the time.
