Thanks @Someone, I’ll check that out 
I got to sleep eventually. I woke up on the sofa and slumped back to bed. Woke up a little bit later again but oh well, glad I switched my WFH days! My insomnia tends to come in cycles so hopefully that’s it for a while…
In that case you maybe should consult a doctor? Anyway: It’s important not to panic. If you say to yourself “I have to sleep, I have to sleep, why can’t I sleep?” you make the situation even more worse. Let the pessimism insomnia win! 
As I pointed out above it’s important just to relax and calm down. And find a place where you feel comfortable. A relative of mine can sleep on the couch much deeper, better and faster than in her/his own bed. 
In my case it worked, last night.
It doesn’t happen to me that much anymore – that was the first really rough one in a while. But I’ll keep an eye on it
Ermagerd I’m so glad it’s bedtime.
I’m staying here for a while. So if you need someone to sing you a lullaby …
…ask someone else?
You don’t know my voice! 
Oh yes I do…
(Damn. I really hoped that it won’t get public…)
Aw fanks 
thankfully I slept much better last night, phew!
Hello, insomnia, my old friend…
I’ve come to chat with you again,
Seeing visions at three a.m.
Are there others as wired as I am?
Needing the sound of silence.
Raises his hands who has read those lines while singing in his mind.
I’m at the gym. If this buggers up my sleep again I’m not going anymore!
Hope not, otherwise I´d have to console you again.
As long as you do it no later than, say, one hour before going to bed I don’t think it should?
Yeah it’s weird - I’ve been going in the morning. I end up really fidgety when I go to bed because my muscles just won’t relax. It’s not like cramp. Difficult to explain. I did make sure I warmed up this time though, which may help.
Have you asked a doctor about that, yet?
The muscle thing? It’s only happened a couple of times so I’m not resorting to that just yet.
