      Hiya Cassie – its to do with our ears and how we sence balance. In our inner ears there is a fluid filled cavity. As we move the fluid moves and bounces on cells that suround it – these send the signals to our brain which works out which way up we are and how we are moving. As long as the signals from our ears match what the eyes are also telling the brain all is fine. But when you spin around it takes a while for the fluid to stop moving – so the brain get different signals from the ears and the eyes – that makes us feel dizzy. Its the same with travel sickness in car and boats etc. The miss-match of info makes up feel sick/
      Hope that helps
