Are these possible in a lucid dream? Explain.

1. Practice on an instrument you've never played / don't know how to play
2. Experience a memory exactly
3. Tell subconscience to come up with a great song/book/etc.
4. Consciously control 2+ selves/bodies/minds
5. Send out a clone of yourself to do something like practice a skill (this works normally in dreams, right?), and then reabsorb the clone and his experiences
6. Remember or have subconscious tell you some obscure information (question 18 on the chem test 2 years ago)
7. Conjure god/spirit guide and have him tell you something extremely insightful
8. In real life, skim over a passage from a book w/o actually reading; recall in dream or have subconscious "process" the info (read this in a FAQ on Resources Page on this site)
9. Reread a book you have already read (or if you can't read well in dreams, have a voice read to you or something)
10. Do something like create a language and become fluent in it (if you have lots of time), see if you still are in real life
11. Experience blindness as if you'd never been able to see (maybe you "forget" what sight is or something)
12. Generate motivation/determination that survives when awake
13. Make predictions in dreams that prove fairly accurate in real life
14. Tell you subconscience to do x thing in real life, like have it remind you of something
15. Have subconscious write my essay that's due, or have it solve a complicated math problem (I understand that your creative capacity is enhanced in dreams, so you can solve these problems, but can you have your subconscious do it for you)?
16. *Note: for this next thing, assume that all piano practice time in a dream is equally as efficient in the real world. Your perception of time in ld's is weird, but if you practice piano for what you perceive to be two weeks, then either (a) you feel like you have been playing for two weeks straight but have only really been playing for an hour (REM/dream time in real world) and thus you only have the skill of an hour of playing or (b) you still feel like you have been playing for two weeks because you actually were, in the dream (i.e., time was extended) and you have the skill of two weeks, whereas in real life you were only dreaming/REMing for an hour. Which actually occurs, (a) or (b)?
17. An experiment - just spend awhile counting at the same rate of seconds, and remember the number you get up to. Then when you wake up you can prove that you had a dream for longer-than-actual dream time. You'd have to count for hours lol, but it might be worth it. Or I guess if any of this subconscious stuff is possible, have your subconscious count for you lol. Also, if one does this, could false memories affect how I count? Maybe I spontaneously skip to 4572345 and have the memory that I have been counting that entire time - or can false memories occur in lucid dreams?
18. Be in your younger self's body and have his mind - if your a kid, for example, then you find joy in playing with toys. Or physically implant false memories, as normal dreams do - like I become Harry Potter and actually am him and believe I am
19. Recall a memory from when you were a baby (that you don't remember in real life)
20. Tell a DC to always appear in your dreams and have him tell you that your dreaming (in future dreams)


The main themes of these questions as you may have noticed are relative to these:
(a) how much can the subconscious store in memories (everything?)?
(b) can your subconscious do work, as in these examples:
> if you give it a task like solve a problem and have it tell you?
> find patterns and make conclusions and using you memories actually make you smarter (like using memories to decode a foreign language so you understand it (using memories of whatever you have seen of that language, and "doing work" to solve it), or teaching yourself calculus ideas w/o any prior experience; extreme examples, but you see what I mean?)?
> and similar things, as in many of the 20 questions above?
(c) basically, dreams can link you to your subconscious - what are the limitations/capacities with this?


I know a some of this stuff might seem absurd, but I believe in a dream anything's possible and that our subconscious can store a near-infinite amount of information, so whatever, these are just some ideas. Thanks.
