Unearthing a memory...

Recently, I’ve been having bizarre ‘flashbacks’. Every time it happens I sense a strong emotional attachment, but am unable to recall anything visual. Seemingly random things bring on these ‘flashbacks’, unfamiliar things, like songs I haven’t heard before, pictures in books, and even faces in the street.

It’s as though I know full well what it is I was feeling at the time, but am unable to recall an image of whatever it was I was feeling that way about…

Basically I’m looking for advice. Can anyone help me recall whatever this is?
