camper bed a bit claustrophobic, anyway to get over it

I finally was able to camp a few days in my camper and each night woke up a bit claustrophobic. The living room area is fine as there are 2 pop outs but the bed area is a bit tight. Leaving both window shades open and the window over the bed helps a bit. Dont want to get rid of the camper as I finally got in dialed in.

Anyone have experience getting over this?
