lucid obstacles

[changed]

When ever i become lucid there is always something wrong it just really frustrates me. I know it is just restrictions of my mind but i don't know what to do. common example: I try to fly through the roof. If i'm even lucky enough to get through the roof i spin around out of control lose complete vision and wake up with sp and halucinate me floating out of bed then i wake up. Aother common example: say i want to fly and i decide to go outside instead of going through the roof. I try to fly but i can't even lift off the ground then i waste a whole lucid dream trying to fly. Another example: i want to spawn some one or something using passive control so i leave the room and repeat over and over again such and such is going to be there when i walk in. walk in and there is nothing. I got good at attaining lucidity i even got up to like 3 or 4 lucids a week but there was always some obstacle. This why i gave up lucid dreaming. this was a year ago. please help me!!!!!
