The moment in time does not matter, you can perfectly meditate within a lucid dream in the context of long time ago in a galaxy far away. The only thing important is you are to mindfully observe this, your attention must not be charmed by anything. Muscle tension does not matter as long as you don't let it distract you. The quality of attention is what matters. You won't have to sit for too long (in fact you don't even have to sit, shavasana is a perfect position if you manage to avoid falling asleep) and you will achieve the goal quickly if you manage to maintain perfect presence and awareness for just some minutes. Needless to say most of the people can't achieve this easily so they have to train for many years but I've found out attention and perception augmenting drugs can help a lot if you have proper motivation, guidance and your brain is ready for this.
