I am trying to draw this picture:

I have tried a lot of things, like defining this

newcommandirregularcircle[2]
pgfextra pgfmathsetmacrolen(#1)+rand*(#2)
+(0:len pt)
foreach a in 10,20,...,120
 pgfextra pgfmathsetmacrolen(#1)+rand*(#2)
 -- +(a:len pt)
 -- cycle

But it don't give a figure that can be between the x-axis and the circle, and I don't know how to do this. Thanks.

One possibility is tp build up a random list and plots a smooth curve through it.

documentclass[tikz,border=3.14mm]standalone
usetikzlibrarypatterns
begindocument
begintikzpicture
 pgfmathsetseed9
 foreach X in 0,...,11
 ifnumX=0
 pgfmathsetmacromyradius2
 xdefmyLstmyradius
 else
 pgfmathsetmacromyradiusmyLst[X-1]+0.5*(rnd-0.5)
 xdefmyLstmyLst,myradius
 fi
 xdefmyLstmyLst,2 
 draw[pattern=north east lines] (2,0) -- 
 plot[smooth,variable=x,samples at=0,...,12] 
 ([xshift=2cm]-x*10:myLst[x]) -- (-60:2) arc(-60:0:2);
 draw (120:2) arc (120:-120:2);
 draw[-latex] (0,0) -- (5,0);
 draw[dashed] (2,0) -- (2,-pi);
 draw (2,0) -- ++ (-120:pi);
 draw[latex-latex] (2,0) + (-120:2.7) arc(-120:-90:2.7) node[midway,below]$mu$;
