The correct answer to this open question is the following.
Although the question is incomplete and does not provide any options, we can say that these bland, thoughtlike ruminations about real events are best described as sleep mentation. Experts define sleep mentation as the thoughts and memories while you are sleeping. When an individual is at the REM sleep, it usually has imagery and thoughts as part of its dreams. That is why when the individual wakes up, some times it can remember some ideas, lines, dialogues or conversations for a short period of time That is why each time you awaken, you're aware of vague mental images that reflect a conversation you and your boss had about resolving a problem at work.
