The probability is that you do not have repressed traumatic memories. It is worth noting that no survivors of the Holocaust have had any difficulty in remembering their traumatic experiences. It is much more common for people to invent false memories, than for them to repress actual memories. As for the significance of trivial intrusive memories, even a catchy song can create an intrusive memory or "earworm" as it is amusingly named. It does not necessarily have any deep significance.
The thoughts are probably not entirely about the trivial thing, but are part of a larger mental condition. Intrusive thoughts are common with conditions such as post-traumatic stress disorder, depression, obsessive-compulsive disorder, and attention-deficit disorder. If you have such thoughts, you should schedule a visit to a professional therapist or even a psychiatrist to see what's causing them.
Of course, the best person to answer that is the person's medical provider. A person with dyspraxia can have a number of psychological, emotional, and behavioral disturbances. It is possible that intrusive thoughts and memories over things that they may find trivial in nature may be a sign of dyspraxis, but without being seen by a professional, it is difficult to say if dyspraxia is the cause of these intrusive thoughts.
Trivial things can become traumatic for a person if they trigger past unresolved trauma or if they are seen as symbols of bigger issues. These triggers can activate intense emotional responses and create a sense of distress or fear similar to what is experienced in PTSD, emphasizing the need for appropriate support and coping strategies.
Its hard to control. But you can think and self examine yourself with thoughts and try and convince yourself to ignore what bothers you if its not a big thing.
