Not sure why you would want to take a decent amount of LSD and go to sleep, but from the trip reports I've read from people who've done this, they all woke up.
If you wan't vivid dreams try Calea zacatechichi, it's extremely nasty to drink, no seriously it's not hard for you to throw up, very bitter, but it works for me. You do need to drink a lot of it, and it's probably not worth the effort, it's quite an ordeal to chug it down.
What also helped me to dream very vividly is St. John's wort, but I also have to drink quite large portions of it, but it definitely works.
Also be careful with this, it's a mild anti depressant, research it beforehand.
