How could we trust our consciousness ?!

[Alan V]

He has done extensive work in the area.

It's interesting that the speaker divides the self into the proto self, the core self, and the autobiographical self, and says we share the first two with other animals with brainstems. That makes the experience of a self (not self-consciousness) a much earlier development evolutionarily than we often take it to be.

I prefer defining consciousness as awareness filtered through a self-concept, which is similar to the combination of mind and self which your speaker made.

Awareness can be passive. Light strikes our eyes and our brains create images from that information. What does consciousness add to such relatively passive awareness? I would say it adds focus based on self-motivated goals. We actively select out certain aspects of the total information around us in accordance with our goals, like road signs when we are driving somewhere. In other words, we limit our total possible experiences based on our self-interests.
