This is your experience. Most of my DCs are numbskulls who can't answer anything. Some of them lie, and I lie to them sometime (intentionally and unintentionally).

However rarely I do have dreams where I learn something.

Some dreamers have DGs and SGs that give lots of useful advice.

Tibettan Buddhism has the concept of dreams of clarity, where true information can be acquired. Why should we care what they say? Well, they've been teaching LDing for over a thousand years. If you read ETWOLD you will see that they also had an influence on LaBerge who is an acknowledged expert in LDs.
