Partial definition

It seems that daydreams can be divided into two large categories: Possible and Impossible. Within those two would be Good and Bad. This might seem too judgmental for some of you, but I like the clarity of these opposites. 

The Possible are those that one may reasonably expect to accomplish. The Impossible are those that one may reasonably expect never to accomplish. These might include expecting that you can (on Earth) fly by flapping your arms. In other words, something with which you have the same chances of winning a big lottery jackpot. Including winning a big lottery jackpot. The Possible includes things like opening a restaurant or taking a cross country motorcycle trip. One must allow for the kind that Albert Einstein had as a child that formed a question that was answered by the Special and General theories of Relativity. Those that seem impossible but can be tackled by indomitable intellect or perseverance.

The Good are those that are likely to have a positive, constructive or happy outcome. Acquiring a puppy or creating a piece of sculpture or doing volunteer work. The Bad are those that are likely to have a negative, destructive or unhappy outcome. Destroying or causing harm to people and or property.

I experience all four and have a tendency for each at different times of the day. For instance, the end of the day is the time that I have the most fun daydreams. Possible or Impossible. The beginning of the day (or work day) is the worst for me.

The assumption here is that these are fantasies in which one places oneself and feels as if it is happening. Are these simply fantasies? I think that daydreams should be  taken more seriously than fantasies.
