I have two questions first one is related to myself and the other one is just a general thing I've been wondering about.

1. A couple months ago my mom mentioned me seeing a boy die from heartfailure in school when i was maybe around 7-9 years old. I don't remember why she mentioned it so don't ask
I do remember that the boy died and the details of his death. But I remember it like I was told about it and not like I was actually watching. When I asked my mom if she was sure I actually saw it she became unsure.
I know it's possible to completely shut out traumatic memories but I have been extremely curious as to wheter I saw it or not and I was wondering if I could find out in a lucid dream somehow?

2. If someone has traumatic experiences would you be able to give yourself therapy through lucid dreaming? Like exploring your traume and comming to terms with it etc.?

ps. There is one detail about the boys dead that I hardly think I would have been told about cause it was pretty gross. But again I do in fact remember it like i was just told about it.

Can't wait to see what you answer guys!
