Not even a dream but I’m concerned

Date: 4/11/2019

So I can’t remember my old accounts crap and made a new one😂 just to ask this but has this happened to anyone else cuz Jesus. So I was using a free calling and texting app for my boyfriend because my phone was off at that time and so at night we would fall asleep on the phone and this weird crap would happen. I’d be asleep and out of nowhere wake up to people talking to me like what the hell. It happened maybe three times before I tossed the app but one time I woke up to this weird lady maybe she was speaking another language or something I can’t really remember but she was calling out for someone and I was honestly not even fully awake so I was freaked and just laid there frozen quietly waiting for them to stop talking because I didn’t know what was happening. She stopped after a minute but because it happened again with another person and scared the crap out of me I reported a problem to the app people and told them people were glitching into my calls and they never replied or acknowledged me? Haven’t used one since to call so idk
