Well, try to consider that if that interpretation is relevant, it doesn't have to be negative. Perhaps you feel that something awful inside you is dying, which would be good, but still alarming. Your dream also makes me think of the recent hurricane tragedy and so your dream could simply mean something like 'tragedy is significant, take note'. Since you are confused about exactly whether the message was about whole or partial 'disintegration' , that may be the best key to moving forward with your interpretation. In math, like the mind, in my opinion, zero and infinity are strikingly similar. Total disintegration could mean unification... when all the parts are gone, a whole remains.

I am not a therapist, so take my advice with this in mind...
