Nested Dreaming

This has happened in the past couple of days. I have been seeing what i have called them "Nested Dreams" . In the first it almost went recursively, i don't remember a few details clearly but i went something like i was having PJ Session with someone. It was really funny. I distinctly remember that it was funny and some part of me told me that i was dreaming and i looked carefully and i found the PJs really funny. But then, i didnt remember anything in the morning. Then , i woke up (in my dreams) and told Shiva that i saw this funny dream. After sometime, i realized that i was still dreaming. Then i slept off. I woke up and told shiva about all this but i again realised that i was dreaming. Dejavu. This happened another couple of times. There was this another time where i kept the same sequence again till i was pained. And then last night, i was in a class and this time, i was putting some PJs in the class. In the Morning, i told Shiva about this class, and to my surprise i found that i was dreaming.
