1. You'll start dreaming about another life, it will feel as real as if you are living it right now.
2. Your memories won't necessarily arrive in order.
3. You can't make it stop.
4. As long as you're not a dick to people on the Network, mostly everyone will be sympathetic to what you're going through.
5. If you think you might become something dangerous, it's a good idea to start thinking about how to stop that now, rather than when you are actually dangerous.
Maybe that will help you.
I've made my choice, but my destiny was determined before I was born.
