When I'm mixed (and going into mania) I get dysphoric. That means you get super irritated and aggressive, anxious etc. I also start to hear sounds like a cell phone ringing in the next room. Last time I woke my bf up and 3am and told him to get his ringing phone from the living room. He looked at me like I was crazy as I seen his phone right in our room the whole time. It really messes with you. And ALWAYS lack of sleep. I'll sleep for about 2 hours at a time. It's not fun for me at all.
