Omg I have those exact same symptoms. I’ve been researching loads and it’s old the fact no one knows what it is and when you tell doctors they think you’re going mad but you aren’t of course. I know exactly what you’re going through- I get voices and everything around me speeds up. I’m studying biology at college and I plan on doing it at university and I’m going to look into it because it’s very odd and people need to know how to deal with it because I know some people get anxious and frightened about it as it just comes out of nowhere and you cannot do control it.
Stop Googling symptoms, your life will be a whole lot less stressful. Life is just odd sometimes. If you're feeling good and life is going well, don't look for trouble, because on Google everything looks like catastrophe if you don't already have a diagnosis from a medical professional.
