Sounds Pigs chirping for the first time

Hi everyone! I just wanted to share what happened last night with my pigs and see if anyone has thoughts on it. I've read on chirping that the meaning is not clear.
I was up really late last night and went into my pigs room at about 3am. I was just refilling their hay and petting them, I pet Mimi my pig I've had the longest first, and she was acting normal just eating hay. Then I went to pet Lulu and at first she acted normally but then when I pet near her eye to brush away some stray hairs she bolted under her hammock, froze into a trance with bug eyes and started chirping rapidly...I thought I had scared her really badly so I just watched quietly for a little, then my other pig Mimi walked up to her and licked behind Lulu's ear seeming to be affectionate, when Lulu didn't respond Mimi froze too and started the chirping as well. They were both standing there chirping, I left the room to get my boyfriend because I was kind of scared and it sounded like a UFO landing. When we came back Mimi had stopped and Lulu was then standing in the middle of the cage instead, but was frozen and chirping again. She didn't seem to be scared because she wasn't hiding anymore, just standing out in the open. I put her favorite treat by her and got no response. Mimi was just walking around doing her normal things and had stopped paying attention it seemed. After a little longer I just petted her on the back and she calmed down and stopped chirping, then went to lay down.

I wish I knew what it meant...Is it normal for both of them to go chirping at the same time? Anyway it was definitely strange and I wish I'd gotten it on camera

Are you sure they're chirping? I've had several chirpers, and they've NEVER chirped at the same time. Usually it's a solo activity, and everyone else freezes. They've also stopped immediately when anyone made a noise or came toward them, so the fact that you could interact with yours makes me think they're probably not chirping but doing something else.

Hi patters! I am really sure it was chirping, I watched the videos on youtube to hear and it was the same exact noise, just like a bird, and very loud we could hear it from the other rooms of the house. Mimi did freeze and watch for a bit, then licked behind Lulu's ear, then joined in the chirping, at which point I left the room to get my boyfriend. When we came back Mimi had moved on and was just walking around, stopping a bit to watch Lulu but not totally just frozen. Lulu had come out from hiding when I left the room and was frozen chirping in the middle of the cage. She was in a total trance, I waved the treat in front of her and there was no response at all, no looking flinching or even sniffing her nose. She only stopped when I started petting her, which I didn't do right away because I was afraid you shouldn't touch them when they were doing that.

I've heard them chattering their teeth at each other and things like that, this was totally different and was exactly the chirping bird noise/trance I saw in videos of chirping pigs.
