I have intuition in another sense which you don't mention here which is the psychic power and precognitive sense. So it is more alike to your first definition than the second one.

The second one I think is more like thinking or imagining or scenarioizing and like you identify I think that can be an expression of anxiety... But it can also be what people do deliberately in brainstorming or policy planning sessions to come up with all the possible kind scenarios they might face.

The psychic of precognitive intuition is similar to your definition 1 in the you're basing interpretations on sort of accumulated experiences, so the thinking without thinking the learned procedural memory, subconscious associative.. but it's important to make the distinction that those interpretive functions are distinct from the sensory functions: where the data is actually coming from. You're not generating the data from your subconscious experience you're sensing the data that is coming ostensibly from outside of you (I don't really understand how that part works but I have some theories) and then you are using your interpretive apparatus that includes the things which you list into your definition 1 to aid you in interpreting that data into some usable form.
