It doesn't seem that you have a problem with exes dreaming. To me it sounds like your having trouble sleeping. Possible stress is keeps waking you up from your dreams then does not allow you to sleep any longer. I'm not sure whats causing it but it is not related to excess dreaming, your just remembering more dreams from waking up in the middle of them.

Also welcome to dream views! If you wanted to when this happens you could try not moving for a couple seconds to a minute and go right back into the dream and have a lucid. Check out the DEILD tutorial in the tutorial section.
