Wishing all new members a warm welcome to the forum.

my LD moments before LD4all were only extremely short too. Keeping a DJ will help you keep focused on dreams and lucidity.
Weird dreams can be fun 
Reading the tuorials/articles and topics on LD4all will give you tools to improve your lucid abilities.

I could understand your post easily. Being a member of an English speaking forum will really improve your English over time. 
It sounds like the LDs you do have are of a very good quality. 
Some members have tried to share dreams. There is also a Chroniclers group who aim to meet up on Sky Island. You may also like to read the Big Shared Dreaming topic which is currently on part III LINK
I love the part in that movie where the street scene is bent until the road is above them! Would be fascinating if I manage to do it in a LD.
Good luck! Try rubbing your hands together next time you realise you are dreaming. It helps to keep the dream stable.
Good luck and I’m keeping my fingers crossed for you to manage the LD4all August mini quest 
I hope you all enjoy your time on ld4all
