Thankyou for your response CanisLucidus. Yes I mean continuing a dream from where it ended by going back into it. I have had some lucid dream experience which can be seen in my dream journal from October and earlier this month. They were quite spontaneous although I had been visiting here more and trying simple techniques like repeating to myself I will lucid dream like mantra. Also I tried visualising what I wanted to dream about and reminding myself I'll be dreaming soon when falling asleep.
