confused or correct analysis!

It could reflect on the state of mind, yes, but some are just experiences, so it's not as clear with that type of group where a situation that happened or not, or something you have or not. Some groups would be part of a catalog of experiences that may have an influence on the individual, separate from their state of mind.

some people only explore/portray small aspects of their lives/selves on here.
maybe a rough outline but no more than that.

Depends. Are people answering honestly or are they choosing groups to draw people or certain age groups in? Like pedos as an example.
