Swamped

You consider knocking anyways. Maybe a soft tap will be enough, it just has to be heard on the other side of the door. Especially if you wait for a moment that's loud to begin with...

And you think you might just get your chance. A rather large and muscular woman has just grabbed a fallen table and is swinging it towards somebody else.

You don't watch what happens next. You just focus on using the noise of the table breaking to cover your knocking.

...And it feels strangely soft. Cold and metallic, but not hard. Your hands feel like they're sinking into it slightly, not making any noise.

Why are you just standing there knocking on air? Hurry up!

What? They can see you? And not the door?

Is this door just an illusion? You try reaching past it, but your arm refuses to go further than what you can see. This is very strange.

Now what?
