Is it normal to have flashbacks of being molested?

i am now 30 years old. for the past lets say 6 to 10 years i have had these flashbacks of something bad which happened when i was maybe 5 years old. its about my uncle doing bad stuff to me in his moms garage. i cant seem to remember exactly what, but afterwards he will tell me i must keep quiet or he will hurt me. i seem to picture him with a friend of his and me in the garage and they doing stuff to me. about 12 years ago i found out he is gay. everytime with another guy. i wont be surprised if he has aids. is it possible to have a memory loss for long and then lets say after 15 years you get thir flashback that might just be true? i never spoke to anyone abou it. i told my mom 2day...
