Random early pregnancy symptom

I’ve not taken a test let me be clear. I was just wondering if anybody has experienced this in early pregnancy.

The feeling when you are either waking up or falling asleep. Personally I get a shiver-like feeling and it’s almost like I’m floating. I’ve always got this when falling asleep or waking. But now I’m feeling it almost constantly, which has never happened to me.

Any weird sleep things that happened to you before BFP? I’m sure it’s nothing, but then it’s also definitely happening and I don’t know why.

Any experiences appreciated!!
