do chameleons have nightmares? I ask because every so often at night I hear a hissing sound and when I go to check every1 is asleep
No one really knows for sure.
The anwser is probably no, because a reptiles brain are not that evolved.
The reason why animals dream is not even clearly understood, and it has
been scientificly proven that more animals do dream then we used to believe.
It's also been demonstrated that REM neural function is not needed for
dreaming as was thought.
The ganglia needed for a dream state (maybe not as we know it) is not known, or I should say, understood.
Trouble is, no one wants to spend the big $$$$ for research this esoteric.
I personaly believe all animals have their own unique dream state which would be totally different then any other animal.
So, I like to think our little friends do dream
