Night time vivid dreams / hallucinations

Okay so this is so weird, for the last two night I keep having these crazy dreams that when I wake up they’re still going. I’m 7 w 3 d pregnant. Two nights ago I swear I was hearing a newborn baby and I got out of bed and walked around to make sure it wasn’t my 4 year old. It’s nothing at all. Last night I woke up thinking I heard running water and went to all upstairs bathrooms checking everything. Like 4am ish both times. What is happening! Is this normal? Does any one else get this? I feel like I’m going insane. 😭
