Traumatic events can take varied forms. They can be intense traumas that you easily remember. They can also be the accumulation of lots of little trauma when there is a pattern in your in which you get repeated abusive or non-empathic encounters. These patterns can extend back to your earliest formative years and you may not remember them, but your dream self tries to communicate how these patterns affected you.

Regarding a therapist, the way therapy works is that you find a safe place where you can open up. So you definitely need to trust your therapist. It can take some time to build trust. There are some kinds of situations where a caring, supportive, and skilled therapist can help you in ways your family and friends can't.

Best wishes and hugs to you,
