I noticed this recently as well. Only...my memory is random. I can remember whole song lyrics (for example, i can rap Eminem - Not Afraid, or Space bound, word for word), but i tend to forget something i was told very recently. For instance, last night walking home, im 2 minutes away from my door. My mate asks my to text him when i get in.
I didnt remember until lunch today

And i planned to watch mock the week today today after hearing it was on 20 minutes beforehand. Come 10, i turn over to a random movie instead and switched on my music.
And i tend to forget things i've said to people before, and end up repeating myself a lot.
