Songs that sound like a dream

I'm a very big fan of songs that make you feel like nothing is real and you're flying through space. Including but not limited to:

Comfortably Numb - Pink Floyd

There Is a Light That Never Goes Out - the Smiths

How to Dissapear Completely - Radiohead

1979 - The Smashing Pumpkins

Any more songs that you can think of like this?
