Waking up in a panic

So I got this game in 2016 ish back when you could live in these caves and just before they test ran the XP system.

I have around 1450hrs so I haven't ever really gotten heavily into it - until about 2 months or 400 hours ago.

So... I dunno if its becaust Im getting less sleep, if it's because Im dreaming about Rust (cant recall them if I am but I smoke a lot of weed), if it's due to playing until sleep time or what is really the cause of this.

I feel personally like its a result of constantly training my brain to be in warzone and survival mode lately.

Everytime my Wife wakes me up, I freak out and throw and kick the blanket of then begin saying sorry as its embarrassing kinda and I don't like startling her either.

I used to be homeless in Tennant creek for a few years leading upto the age of 19 then basically a year of the dame in Adelaide before I finally got a place.

Tennant Creek has a lot of similarities to Rust but IRL. Nothing felt permanent there. you roamed in the dark because at least there you don't get seen. Amd It's all very reminiscent of the survival mode I was in then.

But even then I woke normally.

Anyone experienced this weird phenomenon?
