It is not possible to fully understand the facts of your case from your question. There appears to be misunderstanding of sections quoted by you.
You have mentioned Section 155 IPC, but it relates to “Liability of person for whose benefit riot is committed”. This is completely unrelated to the facts of your case.
Another section mentioned by you is Section 18 IPC, which defines “India”, so again it is completely unconnected with your case.
It appears that police would taken the report of your going missing under Section 155 Cr.P.C. (and not IPC), which means that it is a report for a non-cognizable offence. At some places, police would generally record reports of persons missing as non-cognizable offence under Section 155 Cr.P.C., till it is confirmed that the person has actually been kidnapped / abducted or that some other regular cognizable offence is committed.
Though I am not fully aware of the detailed facts of your case, it appears that when you returned, police might have got the medical examination done to confirm whether some offence was committed when you were missing. Though usually statement under Section 164 Cr.P.C. would not be recorded in such case, if they have really done it in your case, it is possible mainly for the purpose of recording the statement before a magistrate so that tomorrow fresh allegations would not be made.
What I have mentioned above is pure guess work, looking at the circumstances, because your facts are not accurate. You are advised to ask the police itself about the accurate facts and the sections, etc. I don’t understand why can’t you directly ask the police about these things, instead of asking such vague question on a forum like this.
