Some people can have tics in their sleep. In all the really old literature it always mentioned that people didn't tic in their sleep but that was found to be incorrect and people can tic during sleep.

Hard to know if the other things are tics really. Throat clearing and swallowing can be a tic, but I know people who don't have tics who do that when they're anxious or nervous. No idea about the heart beating... however, I do know that sometimes I feel a beat in my ear and then after I notice it, I feel very aware of it and I often wondered if it's there all the time and I just haven't noticed it before.

I have a site with a list of Tics on it, Buffheart. It's really for Tourette's Syndrome but it might be helpful for you. Some people on Autism spectrum have some tics too and my son for example has Asperger's Syndrome (autism spectrum) and he was actually diagnosed with TS when he was young as well.
