Thank you both for your answers!
I think the sleep paralysis episodes were just a phase because i haven't experienced them anymore. I'm sleeping better now and not that tired anymore.

I got lucid just a few moments ago. I went to bed early and slept for almost 9 hours. Then i got up and watched some tv but i felt still kind of tired and thought that maybe it still counts as WBTB. So i went to bed and soon i fell asleep. I saw a long quite vivid dream. I was in my room and on my computer. I was in facebook and i actually accepted a friend request. Then it seemed like the color of facebook changed and it felt different. I refreshed the page and then looked at the address bar. It said ''omalotta.com'' although i was in facebook. It was quite funny and then i got scared because i thought i have computer virus maybe. Then i realized that i don't even have a computer in my room. I did a RC and it worked but i woke up after that. I'm really amazed how realistic it all seemed.
