Auditory and visual hallucinations during pregnancy?

I don't know if this is a common thing to occur, because I never had this with my first pregnancy but, I recently found out that I'm pregnant and the last two nights have been very strange for me;

I woke up in the middle of the night (felt half out of it) and saw a sillouhette of a person standing next to my husband's side of the bed. I almost screamed but I kind of shook myself out of it and no one was there, just my hubby sleeping peacefully next to me. I thought, man that is weird..

Then last night I got some random food cravings at midnight and went to make myself something to eat. And out of no where I hear the exactly jingle of my old camera's start up sound. EXTREMELY CLEARLY. However, I don't have that camera anymore or even have any devices that would make that kind of sound... I freaked out and ran to our bedroom and asked my hubby if he heard that and he said he didn't hear anything.

I've never experienced anything like this in my life and I'm not really a paranoid person otherwise, but I'm curious has this happened to anybody else during pregnancy? Should I be worried?

Sorry if this sounds so weird but after doing a little research some people said it can happen but I'm not sure if it's serious enough to talk to a doctor about? Any help is seriously appreciated!♥️
