more nightmares when I have a safe person, anyone else relate?

20F. to give context, there was this one guy (we'll call him Bob) I used to be close with and to put it frankly.. he's the first person to ever make me feel safe/secure.

Whenever we'd hangout (as friends), I'd go back and tell my girlfriends "omg Bob makes me feel something I've never felt before and idk what it is but it's a good feeling".. it took me MONTHS for me to realise that the feeling was that safe/secure feeling. I had never experienced that in my life despite being in one relationship before.

I remember the first time we'd hung out late at a friends apartment and I insisted on taking the tram home but he was like 'No i'll order you a Uber" but i was insisting and he basically shut me up when he said "I would feel better knowing you got home safe". yall that made me feel something....

Cue the unrequited situationship phase... (ya girl is getting over it...) we were super close - texting everyday.. so that was when I realised "holy shit I get nightmares a lot" bc I'd tell him everytime - to the point where he'd be like "did you get a nightmare again".

welp we're basically no contact now.

anyways I feel like before Bob I either got less nightmares or just wasn't aware of how often I got nightmares.

Although as a kid I had 2 reoccuring nightmares/themes.

tldr; Could nightmares begin once you feel safe? - and can that safety be tied to a person?
