I know the studies, actually, anotherdreamer!
Cool that you do as well!

And - Zoth will know more - there is also one with throwing coins in buckets - with lucid dreamers practising in LD having amazing skill rises, without practising in real life..
He will probably be able to say more..

And - we have a relatively new and quite inactive member - MelSchaedlich - but she is a German psychology researcher - and she did a study on what lucid dreamers use LD for.

Her saying hello on here: hello from a researcher

And here you can download her paper as pdf - or read it - from university Heidelberg: Applications of lucid dreams

Soo - maybe she is doing other things at the moment - but there is actual work done.
