Ha! Absolutely! Although that can be something as small as a feeling, or as intricate as a full-blown scene (with the names changed to protect the innocent, of course). At its best, I think fiction writing is a process of distilling experiences down into more and more discrete impressions, and then rebuilding those into our works, so that they fit into particular narratives. For example, to take just one emotion: We haven't all been embarrassed in exactly the same way, but we've all been embarrassed. As writers, we can tap into universal experiences. That's why empathy is such a vital skill for writing.
I try to set aside blocks of time devoted to what I call my writing practice. But, like the hashtag says (ie, #countsaswriting), there are a lot of things that can be done in that space.
Plus, you have to be receptive when the universe just opens up and plops something useful (an idea, an example, etc) into your lap. Being willing and able to set aside what you're doing at that moment and at least capture the nugget of what that's about—for use later—is helpful, too.
