I am interested in the long term effects you describe. It's quite commonly known that there are consequences such as HPPD etc, however this is usually quite immediate. Any specific examples you can provide?
Only personal experiences and anecdotes. Recurring nightmares, anxiety disorders, drug dependency and mild PTSD are all common stories among my friend group of that era. Whether it was causal or not, who knows. We didn't have the foresight to separate ourselves into control groups.
