What Am ? (2)

You can loose yourself in me
You move from memory lane to future park
I can penetrate you with your peace
Or love, or anger or lust
I can make you cry
I taste nothing
And I dont smell
But i can touch your heart
Painfully, gracefully, , affectionately
Some people can read me
Through the portals on the face
Sometimes I confuse
Somtimes I get confused
But everyday I work hard.
Until night fall I close up
And I welcome you into a new world
Where you are detached, free and happy
As I rest to start over again.

...What Am I ?
