Very shrort lucid dreams

[Edd]

Hello, I'm practising lucid dreaming for about 6 months. I have very big problem. My lucid dreams are very short. About 5 minutes in a dream and everything is being blurry and I have false awakening or wake up. I tried techniques for staying lucid like rubbing my hands or shouting, but it doesn't work! I can return to lucid dream using reality check or DEILD. But dream is still short and has worse quality. Last lucid dream from this cycle had very low quality. It makes me mad, because I can't do anything. Non-lucid dreams are longer, some were long for hours, but lucid are short, and I can't do everyting. I had only some LDs which were longer. Really bad, 6 months practise and LDs are still weak...
