Here's the reveal:
You've seen me several times as you pass by
(You really can pass by several times, if you choose that path).
But never acknowledged me. I wonder why... (Well...you can't talk to it of course...)
I'm surrounded by fellow friends (Framed pictures of other people).
Half-way between us our link ends.
(The stairs split in half at the top and bottom, separating the collection of pictures).
To your right, I'm not much to see,
(When going downstairs, you can't see much of this painting on your right side).
To your left I gaze intently.
(When climbing upstairs, you can see this painting on your left).
It's quiet on this side, except when you are near
(On this side of the stairs, there is no creaky steps, and the whispering happens only when you climb this side.)
Half-way up, it's my voice you will hear (Enough said. XD)
Only once, maybe twice...
(You really only hear it once....but it makes you wonder if he will whisper again each time you come close).
I only mean to surprise (It's a scare in this game)
Tick-tock, creaking floor
(The sounds of this room: the grandfather clock, and the creaky steps on the staircase).
Remember my path, you'll pass once more.
(You will have to climb the stairs on this side at least one more time before you finish the game).
What am I?
(The blinking portrait on the wall of the left staircase in Message in a Haunted Mansion).
