I've had a s*x dream about T and it did freak me out, until I was poking around the internet in dream interpretation and found that s*x is frequently interpreted as a desire for connection, not the deed itself. That felt more true to me, that my dream was about a desire to connect.

My guess is that your T feels you (or you believe he will feel you) pulling away from him. Maybe it's not the first time you've felt this way

So maybe your dream is about your wish for T to find a way to connect with you, even though you feel this way.

And like Guy pointed out, you might want to just tell him up front about the way you feel about him not answering your email. And your desire to pull away. He'll help you find a better way than disconnecting.
