Subconscious thoughts

Some people subscribe to the idea that we can have subconscious thoughts (say, from our childhood) trigger emotions based on particular circumstances. Because these thoughts are coming from our subconscious, we don’t have conscious access to them to spell them out, look at them, and possibly change them. I understand those are the thoughts that people try to access through hypnotherapy etc.

What is your take on this? How would those subconscious, “hidden” thoughts fit into the Model?

Thank you!
