How can I remember lost years in my life?...I know that something very important happened from age 5 - 10...I only see small bits of memory...Nothing I can put into understanding it...How can I recover these years w/o going to be hypnotized?

I know my grandparents kept me hidden from something/someone...That is all I can feel...I need to know what/who was the reason they were doing this...It is really bothering me today...There is something I must remember...And I feel I need to do this soon...
