Nauseous, lightheadness, headache,vuncomfortable feeling in new AirBnB.

Just moved into my new airBnb that I will be staying at for 2 weeks. After around 30 mins, I started feeling nauseous, lightheadness, lack of thinking clarity. And my whole body felt weird. Has anyone else experienced this? I'm spirital so I believe it might be a reaction to a new energy environment, but I googled my symptoms and it says that it may be a carbon monoxide poisoning. They specifically do not have a carbon monoxide alarm. Any advice?
