Do you laugh out loud in your sleep uncontrollably?

As I am learning more about myself and what happened to me, I am realising that many behaviours that I thought were just odd or quirks come from what I went through.

Occasionally I will go through phases where in the middle of the night I will laugh out loud and uncontrollably sometimes to the point of waking up my partner and myself. My partner and I thought it's weird but we didn't think much about it. I want to know if anyone else here has had this happen to them? I haven't come across it anywhere else but there have been other behaviours that I didn't realise were trauma responses but then ended up being part of symptoms too.
