Please turn quoting back on in your newsreader.

You have an odd problem indeed. This phenomenon could /only/ occur if an
adequate amount of fuel and air were being admitted to the intake, that
amount increasing with the revs, so as to sustain the increase.

I almost think you have a dirty throttle body that is so filthy it's
causing the throttle plate to stick open.

Low coolant results in surging (like with a big air leak), not a steadily
increasing idle that occurs over 4 or 5 seconds.

Questions (please intersperse your answers):

You say it's "recently" been doing this. When is "recently"?

Had the vehicle been subject to heavy rains or driven through deep water?
Had a collision?

What happened to/with the car immediately before it started to rev like
this?

If you were to let it rev, will it eventually reach redline? You have a rev
limiter, so it ought to go no further than abut 6,800 rpm.
