Absolutely. All my experiences are, and I assume this is also the case for all the other "experiencers" I encounter, (but this can only ever be a hypothesis).
There is never going to be any possibility of "verification", through some "independent" means, that others do in fact, experience things the way I do, or see or hear things the way I see or hear them. I think Descartes figured something out about all this a while back.
Descartes, practising his method of doubt arrived at his Cogito. From that point on, he argued for the existence of god using a variation of an old argument, which ha long since been refuted. He believed we have a priori knowledge. This was refuted by Locke and Hume both of whom were empiricists.
Some experiences can be shown to be shared and not, therefore, purely subjective. To take a simple example, I would expect you to agree with me that it would be stupid to put our hands into the fire. If we did so,we could compare the burns we received and you could se that your were like mine and vice versa.
If you want to argue that our perceptions are no more than some kind of reflection of reality, that is a different matter.
