Every night I say “Sweet Iguana Dreams” to my iguana family members. Some people would think that is a silly thing to say, since iguanas are said not to dream. But I think they do. Iguanas are diurnal, active during the day and they sleep at night. In fact, they can sleep very soundly. I’ve been known to use this deep slumber to move aggressive iguanas or to clip the long toenails of recalcitrant family members.
Usually, the sleeping iguanas stretch out, with their arms relaxed alongside the torso.
I’ve had a few hundred iguanas reside in my rescue over several years. Generally, they sleep quietly through the night. Every now and then, I would hear thrashing in the night and find an iguana asleep, rolling, snapping his or her tail, legs running in place. I believe these iguanas were having bad dreams, perhaps trying to escape a predator. Since they had been rescued, I hoped they weren’t dreaming about fleeing an abusive human.
I gently stroked the disturbed lizard’s back until they woke up, eyes wide open, looking around in panic. For some iguanas, this was enough and they would relax and go back to sleep. Others wanted to be held and comforted, which I was always happy to do.
This article in Scientific American gives a good summary about reptiles and REM sleep. See? They do have the potential to dream as you and I do.
May all your dreams be “sweet iguana dreams,” too.
