Autism and perception of reality

Hi. So this feels like it might be a really weird question, but i dont know who else to ask. Do you ever feel like things in the past didnt really... well... happen? For example, i lived abroad for six years (age 8-14). I'm 19 now. I know it happened. I remember it. I can look at pictures. But i feel almost like i watched it on tv, like it wasnt actually real. When we lived abroad, i felt as if my life in my home country hadnt actually happend. Like i had drempt it, or something. I talked to family over skype, but i still didnt really feel 100 percent.

This also happens with future things, like taking a trip. No matter how many pictures i look at or even when we are at the airport, it just wont sink in. Im going to get a kitten in a couple months. Ive decided. I have the money, i have the breeder. I look at their facebook page 3 times a day. I know im getting that kitten. But something is off.

This probably doesnt make any sense. Its hard because i feel like my brain is messed up, like my perception of reality is off somehow. Sorry for the long rant. Im really hoping some of you have felt similar to this!!
