Hey, welcome to the forums Lunifeste!!

You seem to be doing very well so far and if you stay on track i can say you will have many lucids to come, as far as the grainy, low lucidity lucid dream you had i will give you a few points and things you can try to increase the dream realism so that you can escape that fuzzy/grainy type dream experience. My first lucid dream was grainy but they are improving slowly, but thats just me, others have improved at an incredible rate.

When you next have a lucid dream and you want to increase the realism you may want to try the following.
- Try rubbing your dream hands together, this is said to increase the vividnesss of the dream.
- If you fear the dream is fading or about to end, try spinning round, this has worked for some and not worked for others so just test this to see if it works.
- If you want to increase the vividness you coould try saying "increase the vividness of this dream" and if it doesn't work, try shouting it loud. This mthod has worked for some but commonly makes the dream too real and then the person wakes up so as i said, experiment.
- Another popular one is to ask a nearby dream character to give you something like a pill or a drink that you can have to increase the realism of the dream.
- The final idea i have for you is to ask a nearby dream character what they recommend to increase the realism of the dream, they will tell you something if they are willing and you will believe it to be true and if you believe it to work it will work.

Just adapt on these, you can experiment and play, do as you wish, try not to get stressed about not becoming lucid or what not because stress it the one thing that kills lucid dreams just stay calm and know that you have your entire life to lucid dream, you've done i before so you can do it again! Best of luck to you
