Is This An Anxiety Attack?

Last night, my house was giving me an eerie feeling before I went to go to bed. When I did go to bed I felt warm and cozy until I suddenly felt dizzy and felt like something was sitting on me. I kind of started to shake, but not really. I was over tired too. I've never felt anxiety attacks like this before. Usually my anxiety attacks happen when I can't get something scary or sad out of my mind and I start shaking and can't stop for hours. Could this be a slight anxiety attack? Or did my overtired-ness cause me to feel sick and dizzy?
