Im having these weird hallucinations when i wake up

Ok I'm really weirded out by this and I need some smart person to help me figure out if this is just my brain waking me up for stupid reasons or if It's something else. But basically, ever since ive moved into this new house I've had some really weird hallucinations. For example, one time I woke up to a giant spider creature with a human head staring at me through the cracks of my blinds. It was scary but I didnt think anything of it because I just finished watching a horror movie and instantly went to bed. But even if I don't do something creepy beforehand, it still happens. And the weird part is, when I first wake up I feel comforted by the hallucinations until I become aware and just stare at them. Like a little while ago I had one of a brown poodle next to my neighbors porch, it was on two legs and it was eating something or playing a harmonica. My window was open and when I became aware and I got scared it left (thats what usually happens) and I heard a bark. All of the hallucinations were spaced out pretty far too. Like I could have one and then have another one the next night, or I could have another one 3 months later. Sorry I'm going too into detail but I just want to know if its my brain messing with me or if its some other weird thing with my brain. All I know is that it's probably not real.
