Maybe undergo hypnosis? See if you can recover any neuralized memories?

I remember when I was young, about 16, I took a trip, about 75 miles away, with my stepbrothers mother to visit him at the crazy house.
Along the way we encountered a strange cloud. That's all I remember.
Fast forward 15 years, had seen multiple UFO's since and lost touch with stepbrother and his mom. So anyway I'm catching up with him and his mom and I tell them about all the UFO's I've seen.

She said she'd never seen any, but she said remember when we took that trip? You absolutely freaked out and were so scared when you saw that cloud or storm or whatever.

I had totally forgotten about that until she reminded me. I have no memory of 'freaking out' just a very vague memory of seeing a strange weather system moving in.

Makes me wonder if I knew something was coming along with that weather.
Alot of abductees and contactees report a strange mist before their abduction.
