Yes you should always start writing, but there are some things you may need improvement on. Here's your two paragraphs, in yellow is my comments
As I looked up in a drunken haze the vibrant lights flicked (Flicked on? Flicked off? Do you mean flickered?) i "i" should always be capitalized, also consider comma, semicolon or period here stumbled to the ground and as i looked up You already said you looked up their There* was a silhouetted figure stering staring* at me consider , ; or . here he quickly turns and runs as his gaze meets mine. Not clear if he's running after you or away from you, if he's running away from you he is running away from you WHILE looking at you, so he's running backwards or something as Capital letter at the start of every sentence, you've also said "as I" far too many times i climb to my feet i decide to go after him. Why would you decide to go after a random man in the distance? in a hurry to get out of the club i just catch him climbing Tense is wrong here, dunno exactly what you're saying into the passenger seat of a large black car.try using more descriptive language as oppose to "large black car", show don't tell confused i turn to enter the club again only to be stooped Stopped* by someone and the person inviting me to go with them.It's not clear whether you're talking about two people here or one, you were stopped by someone and another person who is inviting you to go with them, or is the person who stopped you inviting you to go with them, who was the person inviting you? too drunk to care i blindly agree to follow him Who?and he leads me into a small sporty red car .
as i peered in i saw what looked like comfy leather seats as i Stop saying "as I" and make sure your story doesn't become a shopping list. "First I did X, then Y, then Z, then W, the end", it has to flow more than thatsat down my judgment couldn't of been more wrong it was like sitting on rock.on a rock, but good simile i kept maneuvering my body trying to find a comfortable position but had no luck so i gave up and had a look around put a comma here, punctuation makes the sentence seem less confused by this time the person was sitting down next to me. i tried to focus my eyes so i could see what he looked like but no luck my eyes are blood shot and dry but from what i can see the person is a pasty white about 7 feet tall but a skinny person You basically say "I can't see him, but I saw him", makes no sense. he closes the door looks at me as if he is surprised then he said i was expecting you to be a bit taller i myself am 5 foot im just a shadow in his presence.I liked the "shadow in his presence", but I feel the description here is a bit forced he turns to look forward and starts driving and i start to drift off and fall asleep.
i awoke several hours later in a an* unfamiliar room i groan as my arms push me upright. i feel my head as it is aching. i throw my arm to the ground and look around i appear to be in a white room it was completely empty look around I apprear to be in a white room it was completely empty? Punctuation is important, your sentence is a running sentence and makes the ideas confused apart from a window and a door Put full stop here outside the window was a red car i couldn't identify it as i give up You gave up quickly, also another "as I" trying to recognize the car i try to remember what happened last night and why i am hear but nothing but nothing what? the entire the entire what? was just a blur. i lie down giving up on remembering
Notes:
- Show don't tell
- Don't turn it into a shopping list, like "I did X then Y then Z", it needs to be more interesting than that
- Use more descriptive language, instead of "big black car" say something like "A dark sleek car that was longer than any car I've ever seen"
- Punctuation, grammar and spelling are important, you need to know these.
