Feeling mentaly tired after dreaming
During this last years i have started to notice that my Dreams are getting more and more realistic, visualy and emotionaly, for example, if i Dream about my gf dieing/leaving me, i can see all the details happening and feel all the emotions like if it was on real-life, and then when i wakeup i feel a HUGE and inexplicable relieve.
I dont think i have Lucid Dreams because i cant really controll them, or make cool stuff happen in them, like flying, ect.
But im pretty sure have fully rationality, logic, and self-conscious inside them.
I feel like most of my Dreams are very mentaly demanding, its like they put me in some kind of "puzzle" wich iam forced to finish in order to wake up.
Its very hard to explain.
Because of that, i feel somewhat tired (mentaly, not phsycaly).
And it seems that i cant rest my brain properly, because its working during the day and during the night while sleeping/dreaming.
Is it normal to feel like this? Does anyone experience this too?
