According to the theory of special relativity, as an object with mass approaches the speed of light, its relative time appears to slow down from the perspective of a stationary observer. This phenomenon is known as time dilation. However, it's important to note that time dilation does not apply to photons themselves.

Photons are massless particles that always travel at the speed of light in a vacuum. From the perspective of a photon, no time passes at all. This is because, in the reference frame of a photon, the concept of time becomes undefined. As a result, it is not accurate to say that a photon "feels" or experiences anything, including a sense of speed.

It is a fundamental principle of special relativity that the speed of light in a vacuum is the maximum attainable speed in the universe. No particle with mass can ever reach or exceed the speed of light. So, while it's true that time dilation occurs as an object approaches the speed of light, the behavior of massless particles like photons is not subject to the same rules.
