Having Lucid dreams but need help

[DreamBud]

OK so last night i had a few lucid dreams they where pretty cool but i need help on something ill explain it after the dream: OK I find myself on a boat its raining and for some reason i do a reality check and i find myself dream i did a nose pinch and still got air!!!! it was a funny feeling i turn around and I'm in my house now WTF!!! so i walk to my screen door that i can see through its a sunny day i wanna go have some funny with lucid i keep repeating i am dreaming in my head throughout this. So i try to open the door i notice that the door handle is not the one i usually have this one looks old and creepy i try to open but i cant open it when i try with all my strength to open it i squint my eyes closed and cant see and cant open them i try to imagine light or something but it doesn't work and i wake up . Another lucid dream with same problem i find myself walking down stairs and all the sudden say I'm dream and i catch it i remember i read not to try super hard at first for something and work to strengthen my lucid so i touch the handle bars to fell texture to make dream vivid and i think how much these stairs look like inception and the paradox scene so as i am running around the stairs going down i think i wanna have a gun fight as my first goal so as i reach the bottom of the stair case theres a man in a black suit with a pistol and i look in my hand theres a pistol he shoots at me and the only why i can dodge is by going on my back so i do so as he shoots at me again the bullet goes slow motion i move my leg out of the bullets path and turn and shoot him in the heart fast with precision one shot get up see him in pain and he dropped his gun no blood anywhere though and i shoot him in the head i blink and wake up again. OK so the problem is when i close my eyes in dream i wake up not Right away but i do after 5 -10 seconds of blackness and trying to imagine light or open my eyes i cant. so can anyone have a any-tips i am very open minded and will look in anything decently.
