<human>: Summarize the given text in a few sentences.

My boyfriend of 18 months recently moved in with me, he is kind, considerate and helpful but he's affecting my sleep pattern pretty badly.

I work 9-5 full time so I need to have a good 7-8 hours sleep in order to function properly. He works part time but the shift vary between morning, day and evening so his sleep schedule's a little sporadic.

He's a very restless sleeper, he acts out his dreams, has bursts of snoring or mumbling and will sometimes grab me for a hug in his sleep. I suffer from anxiety and I'm a very light sleeper, so if I'm grabbed or disturbed I'll wake up in a pretty disoriented, panicked state and find it hard to go back to sleep. He will accidentally ram his knee into my back or the backs of my knees too, and as I suffer from joint issues so this means I'm in a lot of pain in the mornings for a good couple of hours.

I don't know how to approach this with him and I feel guilty for being annoyed as he can't help what he does in his sleep. At the same time I feel awful at work because I'm waking up about 4 times a night.
<bot>: Boyfriend unintentionally wakes me up frequently in the night, making me tired at work. How do I discuss this with him and what are my options?
