If somebody is interested here comes the rant
Sorry for eventual mistakes and lack of logic =^_^=

Well, I hate to make decisions)
And I wonder... are those variants excluding each other?

Generally I would vote for mixing them up somehow...

Сон Ясона - that's very tempting for me but it's definitely too early imho Riki (Iason??) should do few more stupid things^^ I don't mean porn of course

Variant 2 -kinda spoilerous:p but honestly I would like if there was additionally sth more suprising? Re Riki's next dream - I would skip it unless there will be some crucial info...and I don't know if I like anbody gouging in Iason's head (if so I would prefer amnesia) ...and why erased only that part? it's somehow weird they let him keep Riki

ili ...
okay in that introducing pages Riki was dreaming(about past, or had prohetic dream), Iason was not (and it was for real, or not?XD), now weird stuff starts to happen (well without exaggeration^^ or maybe with) might be that Raulechko stalking Iason, operations, memory correcting, conspirations, Guy, ghosts, vampires itp itd;p and tadam! Iason wakes up and is very very vexed
And suspicious, and might start to question his reality - especially if Riki is all nice to him and he doesn't realize why... And there may actually be some truth in that dreams of his... Or those might be actual memories?

вдохновение оставило меня
A вообще...
Если бы это было up to authors чтобы принять окончательное решение была бы хоть какая-то неожиданность...
