Sleep Ending? (Spoliers)

[FancySocks]

So I got an ending where I was supposed to sleep? And now whenever I open the game it brings me to the scene where Niko is sleeping. I just want to know if I picked the ♥♥♥♥♥♥♥♥♥ ending possible or is there something that I am missing? Also If it is an ending how do I start a new game :P.
