Sorry for not answering about SE. Somatic experiencing is a technique that was developed to help people deal with trauma. The idea is that when bad things happen, that informations can get stored in your body and can continue to cause difficulties later in life. The treatment involves figuring out where stuff is stored in the body and releasing it.

The combination of SE and brain spotting has been so hugely, amazingly helpful for me! I am still in treatment, but I am more confident, less avoidant, less dissociative, less depressed. I am off most of my psych meds. It's been a long process but I am making progress.
