Rae, it is unfair to expect yourself to be "over" something that affected you deeply. The mind doesn't work like that.
Remember that dreams are your brain running over triggered neural connections. If you are feeling stressed and pressured, it jumps to recently used triggers that mean "stress" and "pressure." The emotions in dreams are true, the dreams themselves are not. However, because the images it brings up are not neutral, they can combine into a heavy mental load!
One thing you might speak to your therapist about is ways to unarm the triggers. In other words, once you understand the emotions, you can start managing your reactions to them and make them less stressful.
