Although this concept seems quite subjective, it is something that many people are experiencing and, believe it or not, this phenomenon can be explained by science. Ever heard of Schuman Resonance? This is the frequency at which our planet operates at and for years it has been considered to be at a permanent 7.8 cycles per second. The interesting part about the Earth's frequency is that this seemingly "permanent" frequency is apparently NOT permanent - the number is increasing! Currently the Earth's frequency is about 12 cycles per second and it has been estimated to be at 13 cycles per second by 2012.
So how does this affect time? Well, we have this connection with the Earth's frequency, and our cells actually vibrate at a similar frequency to Earth's. Since the Earth's frequency is rising, the cells in our body innately are vibrating at a higher frequency. When this happens our perception of time actually speeds up. It FEELS like time is going faster, and because time is not "real" (it is a man-made concept), these changes are affecting how we perceive reality.
