Hey EgYpTiAnMaTT91. Welcome 
Yes, I agree with Zataod. Write down everything you remember. In my case, writing down my dreams often triggers more dream memories. Same thing often happens when I concentrate on the things I dó remember, no matter how little that might be. If you remember a particular feeling, keep it in mind and try to visualize some common dream themes/objects/feelings/situations, things you usually dream about (if you can’t remember these, use real life themes/object/… as they are often very commonly found back in dreams). If, during the visualization, you encounter the same theme/object/… from your dream, you’ll usually notice it and it will trigger more dream memories.
Also, stay calm upon awakening. Keep your mind still, don’t force the memories but let them flow gently. Try to use one memory to trace others. Personally, this goes better if I hold the image passively instead of actively. Forcing it will almost always have the opposite effect. At least in my case…
Another thing you might do, is when you go to bed, repeat to yourself that you WILL remember your dreams in the morning. For me, it usually works better if I repeat it together with the hour of my first awakening. For instance “I WILL remember my dreams right upon awakening at 7am”.
And finally, keep practicing, every day. Even if things go very bad, don’t give up! Because if you persist, it will improve one day, especially if you truly believe it. Intention and motivation is one of the strongest subconscious powers.
Good luck!
