I can't understand what I even want at this point.

You can't have an in-depth conversation("talk deep") with someone until you have something to talk about.

Once you know what you are interested in, you can be honest and express yourself concerning your interest in a topic with another person in a way that shows you've given considerable thought to said topic.

Then you really listen to what the other person says, consider it, and riff on that.

Conversation, or "talking deep", is not about being the most correct or knowledgeable("scientists") response, but about expressing yourself, diving in, and figuring out your feelings about a topic by exchanging ideas with another person.
