Andrey, your dream seems quite straightforward in its simplicity, yet even the repetition of the word 'test' can hold deeper significance. The repetitive nature of the word 'test' might symbolize the feeling of being constantly evaluated or under scrutiny, possibly reflecting some of the stress or anxiety you sometimes experience in your waking life. The word 'test' can also suggest a trial or challenge you are facing, either in your personal or professional life. Given that you are in a relationship, this could relate to pressures or expectations within that dynamic, or it might pertain to the challenges of managing your PTSD and the symptoms associated with it.
The lack of other imagery or narrative in the dream might indicate a sense of monotony or a feeling of being stuck in a repetitive cycle. This can be particularly poignant given your reported experiences of sadness and negative feelings upon waking up. It's possible that your mind is fixated on the notion of being tested or challenged, which could be contributing to the nightmares you often experience.
Moreover, the simplicity of the dream might also reflect a desire for clarity or straightforwardness in your life. The repetition suggests that this is a current and pressing issue, perhaps something that is on your mind frequently. It might be beneficial to explore what specific areas of your life feel like a test and consider strategies for alleviating some of that pressure.
