Richard confusion

Richard got home that night, he went to his room, brought out the first aid box, sat on his bed, opened the first aid box and brought out cotton wool to wipe the blood off his Pam and get it treated, and find out that his Pam was perfectly fine, no cut, or injury. He became shocked and started thinking what just happened, was the bleeding in the park a day dream? That strange lady I met, was it just my imagination? What going on? First, he met a strange lady and then the cut on his Pam suddenly disappeared, this is all strange ( he said to himself ). He went into the bathroom for some shower, got out and wore his night wear. He went to bed that night, still thinking about the strange things that happened that day, he kept thinking till he fell asleep at last. The moment he fell asleep, QOD appeared to him and wipe off his memories about the things that happened earlier. Richard had a dream that night, in the dream he met that strange lady in his friend's birthday party. When he woke up, he did not remember anything from what happened in the park, he only remembered the dream he had the previous night. That really got into his head, that made him forget himself, sat on his bed, thinking and asking himself what the dream means.
