We are just the same in many ways if that reassures you. My husband is a snorer at top magnitude. He also "runs" round the bed all night, as well as twitching at regular intervals, rather like Chinese torture.
I used to get cross, even sleeping (or trying to sleep) head-to-foot and hanging on to his legs in a vain effort to keep him still, and he used to get cross because so often I would bale out into the guest bedroom. Then, one day we realised this was for the best because we each have a better chance of a good night's sleep. He would sleep better knowing I could sleep, and I could sleep better knowing I wasn't on the wrong end of the disturbance.
Yes, we're plodding, just like you two, but I think this disgusting virus situation, whilst keeping us safe at home (those with brains anyway), also gives more time for introspection and that can be depressing. We're all busy analysing too deeply maybe.
I'm trying to be grown-up about it all but I have severe cabin fever now, after nearly a year at home (my husband cleans ovens so has had to keep working where we can trust the customer). We had major problems with son and DiL over the years (who hasn't!) so I over-think that situation, as well as the virus problem, the fact that we can't see our daughter in N.Z., or the other one in Nottinghamshire who has a 5 year old son and now twin girls. Add in the not sleeping in the same room, generally plodding, and there you have the perfect miserable storm.
If we can ever return to a bit of freedom, I hope there may be brighter things to subdue the dull stuff. Good luck to you.
