What truly = 'hive mind' ?

[Naruzeldamaster]

I'm going to at some point be writing an alien species (Although only one of them appears in said story) where they are...but they aren't? It's tricky.
They can share physical experiences (Usually pleasure, sometimes pain if it's strong enough.)
They can share information/skills between individuals. Though actual skill sharing is tricky, since some aren't as good at said skills as others.
But they are 'unique' people, through and through. This is the most human side of them (Aside their mostly human anatomy)
They aren't driven by some 'will' like Bees to a queen of the hive either.

I think a true hive mind would be they all share thoughts together. What one feels or experiences, they all feel or experience.

It would lead to far less individuality, and far more likelihood of duty to the hive over any personal feeling otherwise. The Borg are an example of this, I think.
