It seems for myself more than naught, I've noticed I go back to places I've been to before in dreams, usually expanding the areas limits and adding more in. It's usually an area of the places I've visited in dreams before that I've not seen, if tat makes any sense.
An example being, just last night actually. I've gone to a dream water park before that is outside, twice, both times adding and expanding to the area known, last night was a third visit there, and this time there was an indoor expansion to it, so I focused more on that, though the outside was still there and still what I know of it.

This type of thing happens a lot, whether being water parks, a dream cabin, or just a field. Hopefully when I get better at becoming lucid I can actually use this to my advantage
