Five senses plus four more

At the core of Vipassana is understanding the impermanence of all things. Everything we know, we experience within the body as a sensation, either as a subtle vibration of awareness, or through our senses. Everything we experience arises within us, and then passes away.

Our obvious senses include sight, hearing, taste, smell, touch.

According to wikipedia, our senses also include:

Thermoception – the sense of heat or the absence of it (cold)
Nociception – physiological pain (in our skin, joints and organs)
Equilibrioception – our perception of balance
Proprioception – our kinesthetic sense – our body awareness

What about our thoughts? Are a thoughts one of our senses? Or are they a product of a different sensation? They’re certainly something I experience… and something I can even influence occasionally.
